Four new species are found: P. flavipilosus sp. nov., P. longus sp. nov., P. shengi sp. nov. and P. shuimogouanus sp. nov. This paper provides a description of the four species and a key to the genus in Inner Mongolia. [ABSTRACT FROM AUTHOR]

Lithium is one of the important strategic energy metals, which is in short supply in China. There are three major types of lithium deposits: brine and salt lake type, highly differentiated granite or pegmatite type, and carbonate-clay type. In recent years, some new types of lithium deposits have also begun to receive great attention and subject recent research. There are many crypto-explosive breccia pipe type deposits in the world, including copper, gold, lead, zinc, tungsten and tin deposits, but little is known about this type of lithium deposit. This paper introduces the latest research results of the Weilasituo Sn−Li−Rb polymetallic deposit in Inner Mongolia (NE China), which occurs in the middle-southern section of the Great Xing'an Range metallogenic belt. A remarkable feature of this deposit is the coexistence of various mineralization types, including granite type Rb and Sn−Zn, hydrothermal crypto-explosive breccia pipe type Li−Rb, quartz vein type Sn−Zn and sulfide vein type Pb−Zn−Ag mineralization. Among them, hydrothermal crypto-explosive breccia pipe type Li-Rb deposit is currently very rare at home and abroad, which is likely a new type of rare metal deposit that worthy of our attention. This paper systematically summarizes the geology, alteration and mineralization, geochemistry, isotopes and geochronology of the Weilasituo deposit, and establishes a new petrogenic and metallogenic model.

Converting wind energy into ammonia (WtA) has been recognized as a promising pathway to produce “green” ammonia compared with traditional coal-based technologies. As the key part of WtA, Power-to-Ammonia (PtA) has great potential to facilitate the usage of wind generation. This paper proposes a co-planning approach for regional wind resources-based ammonia industry and the electric network (EN). To this end, PtA is first modeled as a flexible power load of power systems with spatial and temporal constraints on hydrogen supply chains (HSC). Then a novel co-planning model of WtA and EN is established to optimize the WtA configuration and the EN expansion. An alternating direction method of multipliers (ADMM) based algorithm is introduced to effectively solve this model. Real data of Inner Mongolia Province in China is adopted to verify the effectiveness and significance of the proposed approach. It is shown that the siting and operation flexibility of PtA with HSC can reduce the expansion burden of EN. The co-planning of WtA and EN can significantly enhance wind power utilization and reduce total investment costs. Furthermore, feasibility analysis on WtA in comparison with coal-to-ammonia (CtA) and ultra-high voltage transmission (UHV) provides helpful guidelines for the realization of WtA.

Fault identification in vegetated area (e.g., grassland) is a major challenge compared to that in outcrop areas. To identify concealed faults in a grassland covered area, a hybrid method combining the temperature vegetation dryness index (TVDI) and the singularity index was proposed in this paper to extract TVDI anomalies associated with concealed fractures in the Sonid Left Banner Grassland, Inner Mongolia, North China. In the triangle space of LST/NDVI (land surface temperature/normalized difference vegetation index), scattered points were concentrated in the areas of partial and full cover, while few data points were in the areas of bare soil with low values of NDVI and high values of LST; this result is consistent with the semiarid grassland landscape of the study area. Although TVDI imaging shows an obvious linear pattern with an NE-NNE trend, which indicates the existence of concealed faults, the surrounding background weakened and reduced the significance of the anomalies. To better delineate the concealed faults, the singularity index was employed to remove the influence of the background and enhance the TVDI anomalies associated with the concealed faults. The TVDI imaging and singularity index mapping showed NNE and NE orientations; this finding is consistent with the regional tectonic framework. Geological mapping footprints showed that the hybrid method is useful to identify concealed faults in covered areas of grassland. [ABSTRACT FROM AUTHOR]

This paper examines two contrasting cases of ethnic-group political activism in China – the Uighurs in Xinjiang and the Mongols in Inner Mongolia – to explain the former's political activism and the latter's lack thereof. Given similar challenges and pressures, how can we explain the divergent patterns in these two groups' political behavior? This paper forwards the argument that domestic factors alone are not sufficient to account for differences in the groups' political behavior. Instead, international factors have to be included to offer a fuller and satisfactory explanation. The paper illustrates how three types of international factors – big power support, external cultural ties, and Uighur diaspora community activism – have provided opportunities and resources to make the Uighur political activism sustainable. In Inner Mongolia, its quest for self-determination reached the highest fervor in the early half of the twentieth century, particularly with the support of imperial Japan. However, since the end of WWII, Inner Mongolia has not received any consistent international support and, as a result, has been more substantially incorporated into China's geopolitical body.

The evaluation of regional water resource carrying capacity has been repeatedly conducted to provide a scientific basis for the local water resource management and the sustainable development, in particular in the water-limited regions. However, the definition of regional water resource carrying capacity and its evaluation method are still arguable. Through a case study of Inner Mongolia, located in the arid and semi-arid northern China, this paper developed an improved method to calculate regional water resource carrying capacity by the combination of the water supply-demand analysis and the S-shaped curve threshold analysis. The spatial and temporal patterns of the regional water resource carrying capacity in Inner Mongolia during 2000–2019 was evaluated at three scales, namely the province scale, the basin scale and the city scale. The results showed that the average regional water resource carrying capacity of the whole province was 0.25 (the full mark is 1.00); at the basin scale, the Yellow River Basin had the lowest regional water resource carrying capacity (0.17) among all the basins, showing that the utilization of the water resources was unreasonable; at the city scale, the average regional water resource carrying capacities in Hulunbuir and Xilingol were both over 0.25, while those in Alxa, BayanNur and Wuhai were below 0.1; Hulunbuir had 25.48 billion m3 water surplus, while BayanNur suffered from an average water deficit of 4.51 billion m3 from 2000 to 2019. This paper has provided a reasonable way to measure the regional water resource carrying capacity using an improved method by incorporating S-shaped curve threshold analysis, which may have a wider application for the clustering and optimization of regional water management. In addition, the spatial and temporal patterns of regional water carrying capacity are beneficial for policymakers in the implementation of the effective water usage. • Regional water resource carrying capacity is evaluated by water supply-demand analysis and temporal threshold analysis. • The evaluation method is improved by considering temporal threshold at different regional scales. • "S"-shaped logistic curves are used to simulate the temporal pattern of water resource carrying capacity. • Spatial and temporal water resource carrying capacity analysis benefits policymakers.

Studies of the East Asian Neolithic have been conducted for more than a century and many attempts have been made to interpret the functions of prehistoric pottery, particularly the earliest ceramics. The unsophisticated pottery discovered in the Weijiawopu site opens a window for the study of early ceramic function. We conducted plant residue analyses of ceramics from the Weijiawopu Neolithic site; the largest Hongshan Culture settlement in Inner Mongolia, China. The site is thought to belong to the early to middle period of the Hongshan Culture, approximately 6500-5500 cal BP. Based on evidence from starch grains, we identified four main plant resources: 1) cereal grains; 2) Dioscorea plant tubers; 3) beans; and 4) nuts. None of the individual starch grains exhibit surface damage, indicating they did not undergo extensive processing such as grinding or cooking. Hence, we conclude that the pottery samples analyzed derive from food storage containers, indicating one major function of early pottery at the site. Furthermore, wild plants are thought to have been an essential part of the Weijiawopu people's subsistence base, suggesting a mixed economic pattern based upon both domestication activities and hunting-gathering-foraging lifeways.

In the past few decades, drought has been a frequent phenomenon in many parts of the world, especially in arid and semi-arid regions. Hence in order to better predict the development trend of drought in Inner Mongolia and formulate corresponding countermeasures for disaster prevention and mitigation, for this paper we calculated the aridity index according to the annual mean precipitation and temperature data of 109 stations covering 1961-2010. The study result indicated that the mean aridity degree was increasing from west to east and was mainly characterized by moderate aridity; from 1961 to 2010 the change of aridity has been decreasing while aridity has been increasing, especially after the abrupt changing point in 1995. Moreover, the decreasing area of aridity took up 82.6% while the increasing area only occupied 17.4% of the whole area. During a 50-year time scale, the annual mean aridity oscillation periodicity was at 49a, 25a, and7a, and Inner Mongolia was still at a stage of aridity that might last for a long time. Regarding different decades, the climate of Inner Mongolia was relatively humid in the 1980s; however, as time went by the area of moderate aridity degree increased while the humidity area decreased in the early 21st century. Therefore, it was clear that the climate was becoming drier year after year. From 1960 to 2010, contours lower than 30 shifted toward longitude direction and contours more than 30 moved in the direction of latitude [ABSTRACT FROM AUTHOR]

The large public building energy consumption (BEC) is the focus of Building Energy Saving, therefore, it is necessary to study the characteristics of BEC to find out the important factors affecting BEC. For this purpose, 27 office buildings in the west of Inner Mongolia Autonomous Region were studied, based on statistical analysis of the researched basic information and energy consumption bill of these buildings. This paper focused on the determination of the significant factors affecting the total and subentry energy consumption intensity (ECI) of office building, as well as the establishment of standardized linear regression models between these selected factors and total and subentry ECI. Firstly, eleven continuous variables, three independent categorical variables, and the climate factor were selected and analyzed the impact on total and subentry ECI by statistical software SPSS20.0, in order to find out the significant influencing factors. Then based on the results of curve fitting, standardized models of total and subentry ECI and their respective significant impact factors were established using multiple linear regression analysis. The regression results showed that the electricity use percentage of the total equivalent electricity consumption was an important factor affecting the total ECI of office building in the west of Inner Mongolia Autonomous Region. Finally, univariate analysis of variance (ANOVA) was conducted between the three independent categorical variables and the total and subentry ECI, and the results showed that these factors had no significant effect on the ECI of office building. Process of the regressive model establishment and the results of analysis of variance could both guide us to propose more targeted energy saving measures. [ABSTRACT FROM AUTHOR]

In the last decade environmental policies, particularly ecological resettlement, have changed China's pastoral areas. This paper explores the difficulty in conserving rangeland through ecological resettlement. The paper focuses on how ecological resettlement policy has been translated into practice, and how the affected people responded with migration decisions. Empirical findings in a pastoral township in Inner Mongolia demonstrate that local politicians have used the projects to stress economic restructuring, promotion of non-farming activities and urbanization. Meanwhile, affected households haved used migration strategies to adapt to the changing economic and social environments rather than the changing natural environment. The difficulty of conserving rangelands and the marginalization of environmental concerns is a result of locally defined modernization development interests and the affected households' adaptive behaviours.

The Han Chinese migration into Inner Mongolia has been an ongoing process. There have been academic studies on such migration, and on Han Chinese peasant migrants and their interactions with the Mongols. This paper is a study of a particular group of Han migrants, known in English as the sent-down youths, sent by the government to Inner Mongolia, in the movement of 'going up to the mountains and down to the villages', or the rustication movement, which reached its height during the Cultural Revolution (1966 -1976). Among the total of 17 million urban middle school graduates sent to various parts of China to become farmers, about 200,000 went to Inner Mongolia. By the mid-1980s the majority of these sent-down youths had returned to the cities and regained their urban household status. Based on works written by those who went to Inner Mongolia, and especially the interviews I conducted with some of them, this paper analyses their experiences, what it meant to them and the impact they had on the ecology and the political and ethnic integration of Inner Mongolia. I argue that the rustication movement as a Communist 'civilizing' project had negative effects on the ecology of Inner Mongolia. The sent-down youths functioned as instruments in the Han demographic and economic expansion and domination, but in the process, as individuals they underwent journeys of discovery of themselves and of the Mongols. To some, the experiences meant more awareness of ethnic diversity and more consciousness of ethnic rights as well as environmental issues. On the popular level, they played a role in enhancing ethnic integration. [ABSTRACT FROM AUTHOR]

Abstract: Renewable energy is one of the possible solutions when addressing climate change. Today, large-scale renewable energy integration needs to include the experience to balance the discrepancy between electricity demand and supply. The electrification of transportation may have the potential to deal with this imbalance and to reduce its high dependence on oil production. For this reason, it is interesting to analyse the extent to which transport electrification can further the renewable energy integration. This paper quantifies this issue in Inner Mongolia, where the share of wind power in the electricity supply was 6.5% in 2009 and which has the plan to develop large-scale wind power. The results show that electric vehicles (EVs) have the ability to balance the electricity demand and supply and to further the wind power integration. In the best case, the energy system with EV can increase wind power integration by 8%. The application of EVs benefits from saving both energy system cost and fuel cost. However, the negative consequences of decreasing energy system efficiency and increasing the CO2 emission should be noted when applying the hydrogen fuel cell vehicle (HFCV). The results also indicate that developing renewable energy is crucial for transportation electrification. [Copyright &y& Elsevier]

Detailed information from global remote sensing has greatly advanced our understanding of Earth as a system in general and of agricultural processes in particular. Vegetation monitoring with global remote sensing systems over long time periods is critical to gain a better understanding of processes related to agricultural change over long time periods. This specifically relates to sub-humid to semi-arid ecosystems, where agricultural change in grazing lands can only be detected based on long time series. By integrating data from different sensors it is theoretically possible to construct NDVI time series back to the early 1980s. However, such integration is hampered by uncertainties in the comparability between different sensor products. To be able to rely on vegetation trends derived from integrated time series it is therefore crucial to investigate whether vegetation trends derived from NDVI and phenological parameters are consistent across products. In this paper we analyzed several indicators of vegetation change for a range of agricultural systems in Inner Mongolia, China, and compared the results across different satellite archives. Specifically, we compared two of the prime NDVI archives-AVHRR Global Inventory Modeling and Mapping Studies (GIMMS) and SPOT Vegetation (VGT) NDVI. Because a true accuracy assessment of long time series is not possible, we further compared SPOT VGT NDVI with NDVI from MODIS Terra as a benchmark. We found high similarities in interannual trends, and also in trends of the seasonal amplitude and integral between SPOT VGT and MODIS Terra (r > 0.9). However, we observed considerable disagreements in NDVI-derived trends between AVHRR GIMMS and SPOT VGT. We detected similar discrepancies for trends based on phenological parameters, such as amplitude and integral of NDVI curves corresponding to seasonal vegetation cycles. Inconsistencies were partially related to land cover and vegetation density. Different pre-processing schemes and the coarser spatial resolution of AVHRR GIMMS introduced further uncertainties. Our results corroborate findings from other studies that vegetation trends derived from AVHRR GIMMS data not always reflect true vegetation changes. A more thorough understanding of the factors introducing uncertainties in AVHRR GIMMS time series is needed, and we caution against using AVHRR GIMMS data in regional studies without applying regional sensitivity analyses.

The complexity of natural resource management is increasingly recognized and requires adaptive governance at multiple levels. It is particularly significant to explore the impacts of government interventions on the management practices of local communities and on target social-ecological systems. The Inner Mongolian rangeland was traditionally managed by indigenous people using their own institutions that were adapted to the highly variable local climate and were able to maintain the resilience of the social-ecological system for more than 1000 years. However, external interventions have significantly affected the rangeland social-ecological system in recent decades. In this paper, using livestock breed improvement as an example, we track government interventions from the traditional era through the collective period to the present market economy period based on a review of historical documents and case studies. Using the concept of social-ecological system resilience, we diagnose the impacts of interventions on livestock breed management in the rangeland social-ecological system, and discuss how these interventions occur. We found that government interventions in livestock breeding have gradually decoupled the pastoral society from its supporting ecological system. During this process, external powers have increasingly displaced the local community in defining the nature of rangeland management. Power asymmetry and discourse have contributed to this displacement. [ABSTRACT FROM AUTHOR]

This paper outlines an investigation on current situation of Spirulina ( Arthrospira) industry in Inner Mongolia, an internal region of China with temperate continental climate. More than 20 Spirulina plants have been established in Inner Mongolia since 2001, most of which are located at Wulan Town in the Ordos Plateau. By the end of 2009, the total annual production of Spirulina in the Ordos Plateau surpassed 700 t (dw), which account for ca . 80% of the total productivity of Inner Mongolia, and ca . 20% of China. Besides abundant solar radiation and enough freshwater favorable for Spirulina production, the three technical strategies contribute to the prosperity and success of Spirulina industry in the region: (1) reducing the cost or investment by overall advantages of rich local natural resources with low cost for Spirulina production, such as alkaline lakes, coal, electricity, and sandy land; (2) controlling the culture temperature and to avoid contamination by building plastic greenhouses on raceway ponds, (3) reducing investment by simplifying the construction of the ponds and the greenhouses. As the result, the growth period of Spirulina has been prolonged from about 120 to about 165 days, the cost of Spirulina has decreased by 25-30%, and the quality of products has been enhanced substantially. Inner Mongolia is expected to become the largest base for Spirulina production not only in China, but also in the world in the near future. [ABSTRACT FROM AUTHOR]

As one of China's five autonomous regions, Inner Mongolia has not been highlighted in the international news, and the Mongols have not demonstrated significant political will for greater autonomy in the way the Tibetans and the Uighurs have in recent decades. Why haven't the Mongols mobilized? This paper argues that the Mongols' lack of aspiration for greater autonomy is in part due to the relationship between Inner Mongolia and Mongolia as an independent kin state. The different trajectories of national identity construction in these two places and the perception of better living conditions in Inner Mongolia have made the Inner Mongols less anxious about their current incorporation within the Chinese state.

Abstract: The No. 6 coal from the Haerwusu Surface Mine, Inner Mongolia, China, is enriched in Al and Ga, which are valuable metal resources that could be extracted from fly ash. However, fluorine in the coal is unusually high (mean 286μg/g) and potentially toxic to the environment in the extraction process. In this paper, a sequential extraction/density separation procedure (SE/DS) was designed to examine the modes of occurrence of fluorine in the coal. The results show that fluorine extracted in distilled water, NH4Ac (1mol/l), and HCl (0.5%) leachates is low, and that in sulfide fraction is below the detection limit. The organic and silicate associations are inferred to account for more than 90% of the total fluorine in the coal. Boehmite and kaolinite are prime carriers of fluorine (the fluorine content in silicate fraction of the boehmite-enriched sample H-14 is up to 1906μg/g, and that of the kaolinite-enriched sample H-29 is 384μg/g). In bench samples H-2 and H-3, a minor amount of fluorine is related to goyazite. The relationship between fluorine and boehmite indicates that they were probably derived from the sediment source region, the weathered bauxite of the uplifted Benxi Formation situated to the northeastern Jungar coalfield.

Land management has made a strong impact on the landscapes, especially in arid environments. Based on historical data, this paper evaluates the role of Catholic churches in the shaping of the Sanshenggong area in western China in the 1870s. Sanshenggong, an arid/semi-arid region located in western Inner Mongolia, was an important Catholic region in the west Ordos Plateau after the 1870s. After the Congregation of the Immaculate Heart of Mary (Congregatio Immaculati Cordis Mariae) (CICM) obtained land from the Maharajah of Alashan Banner, the Belgian priests converted local Chinese (Hans) to Catholicism by lending land, houses and farm implements. By 1949 most people living there had been converted. As a result of intensive land management by the Catholic mission, the arid/semiarid landscape, formerly used as grazing lands, was changed to more intensive agricultural use. This case study exemplifies the practices and the important role an authoritarian religious organisation played in shaping oasis landscapes in arid and semiarid areas. [ABSTRACT FROM AUTHOR]

The semi-private property rights arrangement called the Household Production Responsibility System (HPRS) was started in the early 1980s in Xilingol pasture of Inner Mongolia (China), and stimulated the development of stockbreeding. The grassland has been degrading severely with increasing numbers of livestock. Based on a historical review of property rights regimes in Inner Mongolia and empirical surveys in Xilingol pasture during 2001–2003, this paper assesses the implementation of HPRS and its impacts on incomes of households as well as the environmental impact on the grassland. It was found that HPRS does not mitigate the “Tragedy of the Commons”, instead it has exacerbated the situation. It was also found that co-management of grassland and livestock among a few households presents a sustainable use of grassland to develop livestock breeding. We conclude with the recommendation that small-scale collective property rights systems should be encouraged in Xilingol pasture of Inner Mongolia. [Copyright &y& Elsevier]

The Western Liaohe River Basin in northeastern China is one of the cradles of ancient Chinese civilization. Archaeological records from this region indicate that human occupation began about 8000 years ago and that agriculture and pastoralism were important activities from an early stage. Very little is known, however, about the effects that these activities had upon the landscape. This paper presents the results of a palaeoecological study from a 3.6 m sedimentary sequence in a relict oxbow lake in the Western Liaohe River Basin of southeast Inner Mongolia. The 5400-yr sequence indicates that human activities had a noticeable impact on an apparently open landscape. Buckwheat cultivation began as early as 5400 cal. yr BP with intensification of agricultural activities from approximately 4700 cal. yr BP. Nitrophilous plants such as Solanum and Cerastium, and also Artemisia were growing in the region at certain times, linked with fluctuations in the δ15N record and probably indicative of increased pastoralism and unintentional/intentional manuring. Burning was probably used for clearance of the steppe vegetation for agriculture with a close relationship apparent between increased influx of microfossil charcoal and the presence of buckwheat. Superimposed upon this record of human impact is also clear indication of three significant intervals of climate change between 2900 and 2600, 1200 and 600 and 600 and 30 cal. yr BP. The latter two are discussed in relation to the 'Mediaeval Warm Period' and 'Little Ice Age' apparent in sedimentary sequences across the Northern Hemisphere. Discussions are therefore made in terms of the impact that both climate change and ancient Chinese civilizations had upon shaping the present day landscape and vegetation. [ABSTRACT FROM AUTHOR]

The expanding use of resettlement as a tool for addressing environmental and poverty-related concerns in China calls for further research into its impacts on local populations. Our knowledge of the effects of such resettlement is very limited, particularly in relation to its social impacts. This paper examines the impoverishment risk of social disarticulation as it is experienced by resettlers in an Inner Mongolian environmental resettlement village—Wan Sheng village. We argue that social disarticulation as a risk of resettlement is by no means an inevitable downward spiral towards social oblivion and anomie. Resettlers, in this case at least, have recreated a living, functioning community that provides many aspects of support for its inhabitants. This is in spite of unfavourable construction and increased economic deprivation. It is the adaptive abilities of these resettlers that come to the fore in Wan Sheng, suggesting aspects of rearticulation and cohesion, and not simply disarticulation. [ABSTRACT FROM AUTHOR]

In response to foreign demands for concessions and territories, China’s last imperial court in the early twentieth century executed reforms to strengthen fiscal, personnel, military, and cultural control over its frontier regions. However, in so doing, it provoked an awakening of the national consciousness of the elites of non-Han ethnic minorities there. Much has changed over the past 100 years regarding the governance of China’s frontier territories of Inner Mongolia, Tibet, and Xinjiang, with the diffusion of nationalist claims among increasing numbers of the ethnic minority populace, heightened focus of foreign actors on the humanitarian and rights situations of the ethnic minorities, and greatly extended reach and firmer grip of the central government. What remained unaltered is the “state integration” purpose of Chinese regimes, as manifested in the practices of “internal colonialism” or “ethnic assimilation,” which has led to grievances and resistance by China’s ethnic minorities against the Chinese state.
