Spatiotemporal patterns and driving forces of land-use and land-cover change in the Mu Us Sandy Land, China from 1980 to 2018

The objective of this paper is to verify the land use and land cover change and to relate them with the potential driving forces that have been acting in the state of Santa Catarina, Brazil, during the period from 2000 to 2010. The methodology consists in identifying trends in the land use and land cover change; indicating possible explanatory factors based in factorial analysis for main components and elaborating a final typology, based on cluster analysis. Results include a strong expansion and growing strength of agricultural activity as well as forestry throughout the state and the loss of native vegetation, which points to the need to develop protective actions and occupation and land use regulations, in particular, in the environmental area, encompassing the development of an intensive and mechanized agricultural activity.

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.

Two Stages

This paper analyzes the land use and land cover change (LUCC) of Wuliangsu Lake by interpreting Landsat5 TM images of 1987, 2000 and 2010. In the first stage (1987-2000), the area of mobile sandy land increased significantly, which signed that the environment of Wuliangsu Lake got worse. On the contrary, in the second stage (2000-2010), over 50% of mobile sandy land transformed into fixed sandy land. In addition, grassland gained a large percent from fixed sandy land and swamp. All of these changes signed that the environment of Wuliangsu Lake got better. In the two stages, the area of residential area and farmland increased obviously, large amount of grassland, swamp and fixed sandy land were converted into farmland, so we can predict that the main reason for land use changes in Wuliangsu Lake is agricultural development.
