To study the impact of land reclamation on soil microorganisms, microbial diversity and population structure in the reclaimed cultivated soil were analyzed using Illumina high-throughput sequencing technology, with the original quality cultivated land as the control. The results showed that, in terms of microbial diversity, the diversity of soil bacteria and fungi in the reclaimed farmland significantly improved (p<0.05). The bacterial Chao1 index of XZ2 was 4164.17 points higher than that of ZL (4.45%) and the fungal Chao1 index of XZ2 was 585.49 points higher than that of ZL (41.06%). Anaeromyxobacteria, Bacillus, Sporocytophaga, and other bacterial genera were highly abundant in reclaimed farmland, and the genera with high fungal abundance included Leucosporidium, Pichia, Purpureocillium phanerochaete, etc. SOC, AN, NH4+ -N, AP, and CEC are important environmental factors affecting the soil bacterial community. AK and NO3 - - N are important environmental factors affecting the soil fungal community. The diversity and composition of the soil microbial community were significantly related to land remediation and soil environmental factors, and the bacterial community was sensitive to these changes. Land consolidation can effectively improve soil microbial diversity and functionality by merging plots and reclaiming cultivated land, and it plays an important role in improving soil quality. The results also provide a scientific basis for land consolidation. [ABSTRACT FROM AUTHOR]

Under the background of carbon peak and carbon neutrality, integrating the low-carbon goal into the rural renewal process is not only an important content of land consolidation research but also an inevitable choice for China to achieve the "dual carbon" goals. Combined with the analysis of the current situation of farmland, forest, industry, water, road, culture, and village in the research area of Qiaobei village, Huinan Town, Pudong New Area, Shanghai, this paper puts forward three core problems from the perspective of land consolidation, cultivated land protection and industrial development, short-term and long-term implementation of inefficient land reduction, and the coordination between waste treatment and rural environment. Then it puts forward the low-carbon renewal strategies of industrial localization and quality enhancement, compound spatial efficiency improvement, and resource recycling. At the same time, the carbon footprint calculation method is introduced to estimate the ecological benefits of recycling practices. Finally, it is fed back to the land consolidation project system and research to provide methods and path references for rural renewal in the period of low-carbon development. [ABSTRACT FROM AUTHOR]

: Land consolidation is an important measure to increase the area of arable land and promote agricultural development, and it is the cornerstone of my country's ecological civilization construction. In order to understand the environmental and ecological quality of farmland soil after land consolidation, we took the land consolidation area of Xinbang Town, Shanghai as the research object, and measured the basic physical and chemical properties of the soil, soil animal diversities and enzymatic activities. A comparative study of the changes in soil physical and chemical indexes and biodiversity of two typical reclaimed cultivated land (XZ1, XZ2) and original cultivated land(ZL) after land consolidation. The results showed that the SOC content and CEC of XZ2 significantly higher than that of ZL(P<0.05). The TN of XZ2 was 20.21% higher than that of the ZL. XZ has a lower content of TK. The activities of neutral phosphatase, sucrase, urease and the dominance of soil animals in XZ2 farmland were higher than those in ZL. The correlation analysis showed that Acaridae were conducive to the improvement of soil nitrogen and phosphorus mineralization and CEC. The richness of soil animals of reclaimed cultivated land was high, but the diversity was low. The soil source of guest soil directly affected the physical and chemical properties and fertility of the soil after land consolidation, and different soil sources were adopted according to the utilization needs of cultivated land. On the premise of improving the ecological quality of cultivated soil, ensure the rational utilization of guest soil. This study provided a theoretical reference for the implementation of ecological land remediation projects in the later stage. [ABSTRACT FROM AUTHOR]

The traditional land consolidation planning is just focus on improving the concentration of cultivated land, which could not meet the new requirements for sustainable development proposed by the ecological restoration of territorial space and all-around land consolidation. This paper incorporated multi-objectives, including spatial structure, ecological value, environmental impact, and agricultural production potential, into the framework of land consolidation potential zoning decision-making, based on multi-objective optimization theory with Pareto optimal algorithm. Taking Qingpu district as a case study, a total of 6397 plots, almost 2922 hm2, was classified into the category showing highest potential to consolidate into cultivated land from the trade-off perspective. The methodology proposed in this paper, could better deal with the quantitative solution problem under the multi-objective trade-off, which can provide technical support for the planning and deployment of major land consolidation projects at the district and county level in my country.

In order to explore the soil environmental quality and herbaceous plant characteristics of different land in Shanghai land consolidation area. In this paper, the soil environmental quality and distribution characteristics of herbaceous plants were investigated for four types land: farmland, garden, forest and construction land. Characteristics and their relationship to soil factors. The results showed that: (1) The comprehensive grade of soil quality geochemistry was forest > farm > garden > construction, and the soil nutrients in the garden were not balanced; (2) The herbaceous plants were mainly Compositae and Gramineae, and the degree of species differentiation was relatively high. (3) The species richness index of herbaceous plants is highest in forest and lowest in farm, but the biodiversity is highest in garden and lowest in forest, indicating that due to the influence of forest type and canopy closure, the quality of forest in the survey area is not uniform. (4) The correlation analysis between herb diversity and soil factors showed that: hydrolyzable nitrogen in soil was significantly positively correlated with Shannon-Wiener diversity index and Simpson index, but not significantly correlated with most heavy metals, indicating that hydrolyzable nitrogen was an important factor affecting the investigation, and heavy metals are not limiting factors for herbs. Abundance (S) was significantly positively correlated with available potassium in soil, Pielou index was significantly positively correlated with arsenic. Therefore, the soil should be properly improved with organic fertilizers, and invasive plants should be removed in time, which is conducive to the growth of herbaceous plant communities and the stability of biodiversity.

Shanghai successively carried out five batches of city-level land consolidation projects. Land consolidation processes and technologies have evolved. However, presently, the land consolidation plan is based on the amount of newly added cultivated land, infrastructure construction, among others out of ecology. Taking plants, soil animals, birds, amphibians, insects, and plankton as survey objects, this study conducted an ecological survey on a land improvement project area in Shanghai. According to the survey results, the species diversity of birds, frogs, and insects in this area was relatively high, the proportion of native plants used was low, the distribution of invasive plants was wide, the density of soil animals in irrigated paddy fields and wastelands was low, and the density of plankton in the river was relatively high. There are suggestions to improve the land consolidation plan, such as strengthening the use of native tree species to build a multi- level and multi-type plant community, rationally planning the area of irrigated paddy fields and farming conditions, making good use of wasteland and unused land, and planting a variety of aquatic plants to enhance the stability of the aquatic ecosystem.

Shanghai has been carrying out many municipal land consolidation projects to improve the intensive use of land, increase newly cultivated land, protect cultivated land, and ensure national food security. The landscape pattern of cultivated land is a direct reflection of cultivated land agroecosystems. Based on a municipal land consolidation project in Shanghai, this study selected three typical administrative villages (Village C, L, and N) to analyze the relationship between cultivated land quality and cultivated land landscape patterns at the village scale, using spatial autocorrelation analysis and a geographically weighted regression model. This study provides a theoretical reference for farmland planning for land consolidation projects. The results showed that the cultivated land quality of the three villages was strongly affected by patch density (PD), area-weighted average shape factor (AWMSI), maximum patch area (LPI), and Shannon diversity (SHDI). Village A had the best– cultivated land quality. Although the degree of cultivated land fragmentation was higher than that of Villages L and N, Village C had the advantage of rich landscape ecology and high connectivity. The degree of fragmentation of cultivated land in Village C was mainly affected by the cutting effect of agricultural infrastructure, such as ditches and roads. Modern agriculture was developed in Village C. Reasonable planning of farmland landscape elements such as roads and ditches and improvement of cultivated land quality from the perspective of optimizing landscape patterns can effectively promote the coordinated development of cultivated land production and ecological function.

The development of intelligent technology and equipment for land consolidation is an objective requirement to improve the automation and information ability of China's land consolidation service industry. The status quo of land consolidation and management information technology in some provinces and municipalities was analyzed, as well as its shortcomings in decision-making analysis, land rehabilitation, information islands, etc. Because of the development trend of construction workers and engineers aging out, with consequent loss of their knowhow, there is a growing necessity to maintain and develop intelligence in land consolidation projects. Shanghai is an example because of the advanced nature of its technology and equipment. The authors’ suggestion is that Shanghai provides a scientific guide for the equipment and technology of land consolidation in its use of big data and Internet Plus, survey and evaluation, construction engineering, automation integration, intelligent platforms, and other aspects.

Applying landscape ecological theory to a land consolidation project was the urgent need for land consolidation of Shanghai in the new period, and much importance was also attached to ecological civilization construction and rural revitalization. This study takes Xinbang Town in Songjiang District of Shanghai as an example, abiding by three kinds of design concept: ecological protection, sustainable development, and micro-updating. Specific ideas about the micromodification of five elements--water, farmland, roads, forests, and villages--are put forward: to build a "production, existing, and ecology" integrated recreational space and to create a new rural leisure land for sights where "the water was clear and beautiful, the local species were rich and varied; the farmland was intensive and high yield; the rice and frogs harmoniously co-existed; the village’s vigor was fully stimulated". This study can provide a reference for the landscape ecological design of land consolidation in similar areas. [ABSTRACT FROM AUTHOR]

In this paper, according to the requirements of the Shanghai urban master plan, the city is divided into two major sections of the city and suburbs from the perspectives of urban spatial layout and the urban-rural system. We then divide Shanghai into six land consolidation strategic areas, namely: (1) the center city, (2) the surrounding areas of the center city, (3) the Pudong riverside coastal strategic coordination area, (4) the Hangzhou Bay north coast strategic coordination area, (5) the Yangtze River estuary strategic cooperation area, and (6) the Dianshan Lake strategic coordination area. Differentiated land consolidation strategies are put forward according to the characteristics of these strategic areas. [ABSTRACT FROM AUTHOR]

This paper divides eight municipal land consolidation projects into three categories according to the main source of newly-increased cultivated land: (1) agricultural land consolidation projects, (2) construction land reclamation projects, and (3) comprehensive land consolidation projects. It analyzes the influence of different types of land consolidation projects on the national economy by using the input-output method. The results show the following directly stimulating multipliers of different types of land consolidation by size: comprehensive land consolidation projects (3.51) > construction land reclamation projects (3.40) > agricultural land consolidation projects (2.95). According to the study’s results, the three types of land remediation projects have a significant stimulating effect on the national economy, but the difference is also obvious: comprehensive land consolidation projects are best, construction land reclamation projects and agricultural land consolidation projects successively follow. Therefore, from the point of view of investments with the greatest effect on the national economy, the government should increase investment in land consolidation in Shanghai, and give priority to comprehensive land consolidation projects. Furthermore, if the conditions for carrying out comprehensive land consolidation projects are defective, the government should conduct construction land reclamation projects. [ABSTRACT FROM AUTHOR]
