In order to extract information of the Mathematical simulation model for the references of land useplanning decision, it analyzed the land use characteristics in shaoyang district of hunan province, then extracted cultivated land, construction land and rural residential land. Typical relation analysis method and spatial gridding Logistic regression analysis method were used to made quantitative analysis of these three types of driving forces and obtain the main influential driving forces for each land use.The results showed that it can provide scientific support for the formulation of the relevant policies ,the fitting degree of the spatial simulation was rather high(f construction land, rural residential land and cultivated land was 79.45%, 89.35%, 95.35% ), it showed that the model can provide theoretical foundation for the regulation of land-use behavior,also help promote efficient for land use fundamentally.

The Impact

Current land cover research focuses primarily on spatial changes in land cover and the driving forces behind these changes. Among such forces is the influence of policy, which has proven difficult to measure, and no quantitative research has been conducted. On the basis of previous studies, we took Hubei Province as the research area, using remote sensing (RS) images to extract land cover change data using a single land use dynamic degree and a comprehensive land use dynamic degree to study land cover changes from 2000 to 2015. Then, after introducing the Baidu Index (BDI), we explored its relationship with land cover change and built a tool to quantitatively measure the impact of changes in land cover. The research shows that the key search terms in the BDI are ‘cultivated land occupation tax’ and ‘construction land planning permit’, which are closely related to changes in cultivated land and construction land, respectively. Cultivated land and construction land in all regions of Hubei Province are affected by policy measures with the effects of policy decreasing the greater the distance from Wuhan, while Wuhan is the least affected region.

The Impact

<p>Idle rural residential land (IRRL) is an important manifestation of changes in the human-land relationship during rural development. Studies on this topic are an important field in the study of sustainable land use, but quantitative analyses of IRRL in the academic community are still lacking. In this paper, we take the Pinggu, which has rapid urbanization, to analyse the spatial differentiation of IRRL and explore the spatial differentiation in the impact of different factors on IRRL. Results showed that IRRL was a common phenomenon in metropolitan suburbs with rapid urbanization. It had a spatial pattern of "one belt, three cores" in Pinggu, and its scale decreased from southeast to northwest. Industrial areas, semi-mountain ecotourism areas and urban fringe areas were the high-incidence areas of IRRL, while the idle rate of rural residential land in mountainous areas and plain agricultural areas was relatively low. The IRRL was the result of a combination of different factors, and there were differences among the different factors and regions. The transfer of rural labour, non-agriculturalization of industrial structure and mode of production and lifestyle caused by urbanization and industrialization were the major driving forces, and the lagging village planning and imperfect land use system increased the risk of IRRL. Our study contributes to filling the gap in quantitative research on IRRL to enrich the land use research system by exploring the interaction between humans and land in rural areas and thus has significance for rural restructuring and sustainable use of land in China.</p>

Rural Residential Land

Rural residential land is the main space of a farmer’s life, rural culture, and social relations. Prior research of rural residential land has focused more on its evolvement in plain and traditional agricultural areas. Yet, there is no clear picture of rural residential land expansion, especially in ecologically fragile areas. This study analyzed the characteristics of rural residential land expansion based on 30 m spatial resolution land-use datasets of the Baota District of Yan’an City, Shannxi Province, and further explored the influencing factors and mechanisms of rural residential land expansion through binary logistic regression (BLR) modeling. Our findings indicated that the area of rural residential land in the Baota District increased by 116.16% during 1990–2015. More than 75% of the residential land expansion came from the occupation of cropland. Moreover, rural residential land expansion was heterogeneous in the rural regional system. The expansion scale, speed, and mode diversity of rural residential land decreased with the increased distance to urban built-up areas. Geographical conditions and resource endowments are the primary internal driving factors; urbanization and policy implementation are two major external driving forces. The authors suggest that the realization of regional sustainable development in ecologically fragile areas should strengthen urban–rural integration, focus on constructing central towns, and ensure ecological protection measures.

It is an effective method to study the value change of ecological services based on land use and cover change information. This paper analyzed the land use and cover change information in the research area, which is based on the remote sensing images and social statistics data of 2005, 2010, and 2015, and then, quantitative estimation of the ecosystem service value was performed. Yangtze-Huaihe river basin, China is a fragile ecological area, which is selected as the research area. During 2005-2015, the area of cultivated land and construction land was the main land use types in the study area, the land use and cover change in the study area were obvious, which was characterized by the increasing of construction land area and the decreasing of cultivated land area, and the total ecosystem services value in the research area has been decreasing continuously, the value from 34.376 billion yuan in 2005 to 26.161 billion yuan in 2015.

By analyzing the advantages and disadvantages of Per capita construction land method, Vacant land rate method and Comprehensive evaluation method, rural residential land is classified into two types by using related technologies of ArcGIS according to their condition: one is minor residential area, using the whole relocation model, and the potential is calculated by per capita construction land method and modified by farmers’ willingness; the other is central village, using the internal reconstruction model, and the potential is calculated by vacant land rate method. The sum of the two types is the total potential. And take Pingnan county for example, the realistic feasibility of the several methods used to calculate the potential of rural residential land is comparatively analyzed.

Rural Residential Land

The work of rural residential land consolidation is related to several aspects, such as optimization of the structure of rural layout and improvement of the ecological environment in rural areas. Therefore, the work of rural residential land consolidation must be carried out rationally and effectively on the basis of scientific estimation of the real potential of rural residential land consolidation. However, according to the existing estimation method of the consolidation potential of rural residential land, it ignores the willingness of farmers who are closely related to it and cannot meet the current requirements of rural residential consolidation. Under the background of rural revitalization and based on the new requirements of standardizing rural land improvement work, this study organically combines rural residential land consolidation and the protection of farmers’ land rights and interest from the perspective of farmers’ wishes. The research uses a multimethod integrated approach (the per-capita construction land standard method, per-household construction land standard method, and town system planning method) to measure theoretical potential of the rural residential land consolidation and constructs a correction index system in two dimensions: natural conditions and economic feasibility. And then, this study further optimizes the correction index system from the perspective of farmers’ willingness. Finally, the feasibility of the estimation method is verified by a case. The research will initiate new ideas for estimating land consolidation potential in residential areas and provide references for the work and the special plan of rural residential land consolidation in various localities.
