In 2020, China's poverty alleviation has made decisive achievements, and the regional overall poverty problem and the absolute poverty problem of the rural population in China have been basically solved. But when the national poverty alleviation policy is optimized and adjusted, enhancing the endogenous sustainable development capacity of poverty-stricken areas and households has become the focus of consolidating the achievements of poverty alleviation and comprehensively promoting rural revitalization. Livelihood resilience, which focuses specifically on the ability of individuals to withstand external shocks and disturbances with their own capital, is a necessary attribute for achieving sustainable development. However, previous studies paid less attention to the disturbance of social factors and the driving effect of social environmental factors on the construction of livelihood resilience. Using 518 farmer survey data from Shaanxi Province, this paper explores the mechanism by which farmers individual capital affects their livelihood resilience through ICT adoption. Statistical analysis shows that social networks are the most important factor for farmers to resist risks and develop sustainably. The empirical study finds that farmers' individual capital and ICT adoption are important variables in the construction of farmers' livelihood resilience. Specifically, the more individual capital farmers possess, the more likely they are to have higher levels of livelihood resilience. The higher the level of ICT adoption by farmers. the more they tend to have higher levels of livelihood resilience. At the same time, the impact mechanism of farmers' individual capital and ICT adoption on livelihood resilience shows an intermediary effect: individual capital use of digital technology livelihood resilience. In this path. ICT adoption partially mediates the impact of individual capital on the level of livelihood resilience, and the indirect effect of ICT adoption on livelihood resilience is greater than the direct effect, and the results are robust. Further analysis shows that there is no significant gender difference in the impact of farmers' individual capital on livelihood resilience. Compared with previous literature this paper expands on the following aspects: first, the risk factors of most previous studies on livelihood resilience are natural and ecological. In this paper, the risk scenario of livelihood resilience was extended from relatively sudden natural ecology to changes in social factors, and the construction mechanism of livelihood resilience under changes in the social environment was constructed. Second, previous studies on livelihood resilience rarely included the effects of ICT adoption. In this paper, ICT adoption is included in the relationship between farmers' individual capital and livelihood resilience. Third, most previous literature finds that ICT adoption exacerbates the digital divide between urban residents and rural residents. However, this study finds that in the face of risks, digital technology, as an external social construction, also brings about social integration, and ICT adoption essentially plays a role in the redistribution of resources and factors between urban and rural areas and between regions. An important policy implication of this study is that in terms of effectively connecting the achievements of poverty alleviation and rural revitalization, the path of individual capital-digital technology-sustainable development should be generally followed, which would improve farmers' livelihood resilience and endogenous sustainable development ability in the face of external risks.

Yunnan is located in the center of the east-Asian karst area, one of the three largest karst areas in the world. Rocky desertification is widespread in the area, which seriously restricts the sustainable development of local social economy. In this study, we summarize the research status and achievements of rocky desertification in Yunnan mainly from three aspects, rocky desertification zoning, governance model and vegetation restoration in rocky desertification areas. The results show that rocky desertification areas in Yunnan are divided into 2 large areas and 5 small ones. After years of exploration, 23 kinds in 4 categories of rocky desertification control models have been formed, and 435 kinds of plant species can be used for ecological restoration in rocky desertification areas, including 376 species of shrubs and 59 species of herbs. Finally, combined with geographical location, climate and altitude, this paper preliminarily summarizes the suitable restoration vegetation, and points out the shortcomings in the studies on the control of rocky desertification, so as to provide an important theoretical reference for the subsequent research on the restoration and control of rocky desertification vegetation.

Southwest China is one of the three largest continuous karst clusters in the world; therefore, studies on karst rocky desertification in this area are very important. For more than 20 years' control, the decreasing area and risk of karst rocky desertification has contributed to the continuous ecological improvement. Nowadays, studies on rocky desertification mainly focus on the eight provinces in Southwest China, which have been designated as rocky desertification monitoring areas by the Chinese government. After the first phase of the comprehensive control project for karst rocky desertification in 2016, the expansion trend of rocky desertification in the southwest region was effectively curbed. Subsequent articles published tend to focus on analyzing the current situation, comprehensive management, or species adaptability of rocky desertification monitoring areas. However, the Qinba region in Shaanxi Province is located outside the monitoring area. In the process of studying the karst geological relics of the Zhenba Sanyuan Tiankeng Group, signs of rocky desertification have been found, but there still exists a research gap in the investigation and research on karst rocky desertification in this area which is one of the areas with the richest biodiversity in China, known as "ecological lung", "central water tower" and "biological gene bank". Unfortunately, this area is burdened with poverty, so the investigation and study of karst rocky desertification in the Qinba region of Shaanxi Province is of great significance to ensure green and high-quality development and ecological civilization construction. In this paper, by analyzing the current situation of karst rocky desertification in Southwest China, we summarized its harm to the ecological environment and social economy, clarify natural and human factors resulting in rocky desertification, and integrate the typical treatment experience in Southwest China. We also introduce three technical methods, including remote sensing interpretation, UAV remote sensing survey and analysis of carbonate dissolution rate, to provide a scientific basis for studies on karst rocky desertification in the Qinba region of Shaanxi Province. Study results show that the area of karst rocky desertification in the Qinba region covers 63.37 km², and the areas of severe, moderate and mild rocky desertification cover 17.97 km², 21.60 km² and 23.80 km², respectively. Based on the survey results, there are both regional differences and some similarities in distribution patterns in the areas of rocky desertification development. Specifically, the degree of rocky desertification in the limestone area is more severe than that in the dolomite area. It is also more severe in the area with developed water system than that in the arid and semi-arid area, and the more active the new structure is, the more severe the rocky desertification is. Compared to the Southwest China, the degree of karst rocky desertification in the Qinba region of Shaanxi Province is relatively light, with a smaller distribution area, mainly due to the less rainfall in the study area. The karst rocky desertification in Beiyang mountain of Zhen'an county is the most severe, with an area of 7.28 km². In the 1960s, a large-scale free-range of livestock severely damaged vegetation. The indiscriminate deforestation by humans further exacerbated the process of rocky desertification. The rocky desertification in Hailuogong village of Shanyang county is also severe, covering an area of 5.83 km², because the landform in this area is a typical peak-cluster depression, which is likely developed into rocky desertification. The contradiction between people and land needs to be solved urgently. In conclusion, more monitoring and research efforts are needed in Beiyang mountain and Hailuogong where the rocky desertification is severe. Firstly, we should clarify the causes of rocky desertification in the Qinba region and compare them with the causes in Southwest China to determine whether the rocky desertification is mainly resulted from natural factors or human factors. Secondly, we should know how to clarify the causes of karst rocky desertification in the Qinba region; for example, we can dynamically monitor the change of rock desertification by field verification, remote sensing interpretation, climate change analysis, etc. We can also calculate the contribution rate of each influence factor by geographical detector model. Thirdly, we should further study influence factors of karst dissolution rate. We can monitor physical and chemical properties of soil (soil moisture, carbon dioxide concentration, pH, organic matter content and porosity) in areas with moderate to severe rocky desertification, and analyze the relationship between dissolution rate and physical and chemical properties of soil in rocky desertification areas. Finally, in order to provide basic data for carbon neutrality research in Shaanxi, we should conduct studies on the carbon sink of rocky desertification areas in the Qinba region, with the methods such as dissolution test pieces and hydrochemical runoff.

Green and sustainable development of irrigated agriculture and protec tion of agricultural biodiversity are the inevitable require -ments for the construction of modern irrigated districts in China. However, in order to ensure the efficient utilization of irrigation water, the construction of irrigation channels has been dominated by hard engineering, which has caused the loss and fragmentation of amphibian habitat, and the damage for ecological environment of the irrigation districts. The construction of amphibian corridors in irrigation channels is an important way to improve the connectivity of agricultural landscape and the migration efficiency of frogs in farmland. This paper innovatively applies the hydraulic characteristics of curved channels to the research on ecological channels, builds the curved irrigation channel models, conducts numerical simulation experiment, analyzes the trajectory of frogs at the curved irrigation channels, proposes the design of engineered modifications to allow frogs to escape from field concrete ditches. To evaluate the effects of engineered modification on the effectiveness of frog-ways and the water transfer efficiency of irrigation channels, the paper compares the water flow pattern and calculates the head oss. By carrying out numerical simulation tests, the paper obtains the flow movement law of the concrete-lined irrigation channels with different bend angles, and the flow dynamic axis and velocity distribution are compared. As a result, the slow flow zone and the transverse circulation are found. The locations suitable for amphibian corridors to be built vary when the curvature of the curve changes. The numerical simulation and head loss calculation results show that the amphibian corridors in the bend has no obvious influence on flow pattern and water transfer efficiency, and the head loss in bend is about 3.83X10"4 m, which can ensure the safe and unobstructed water flow. This study is expected to provide a scientific reference and technical support for the ecological reconstruction of end irrigation channel systems. [ABSTRACT FROM AUTHOR]
