1995-2015 年江苏省土地利用功能转型特征 及其协调性分析.

The land use function transition is an important measure to promote the coordination of land use functions and achieve sustainable regional development. This paper constructs an analysis framework for land use function transition based on sustainable development from the perspective of functional coordination, and uses the five phases of remote sensing images of Jiangsu province in 1995, 2000, 2005, 2010 and 2015, as well as related resource utilization and socio-economic data to construct the three level evaluation system of land use function. Taking the county as an evaluation unit, through triangle model and spatial correlation analysis, the spatial- temporal evolution characteristics of land use functions are quantitatively analyzed, and the coordination status of land use functions is proposed for sustainable land use in Jiangsu province. This paper has obtained the following main findings: (1) During the research period, the overall level of land use function in Jiangsu province has increased at a slower pace. The production and living functions have enhanced in different degrees, and the ecological function has significantly been reduced. (2) The spatial aggregation of production and living functions of land use in this province has not been obvious, and the areas of ecological functional hot spots and cold spots have a "Y"-shaped pattern of agglomeration distribution. (3) The sustainable development of different functional areas has not been the same. The sustainable development of key development zones and restricted development zones has been generally good. The sustainable development of optimizing development zones has been weak and continued to deteriorate. In the process of implementing development plans and space planning, we suggest that priority should be given to construct the modern demonstrative region in Southern Jiangsu, the key development zones should be focused on the living function transition, the restricted development zones (I type) should be focused on the production function transition, and the forbidden development zones should be implemented strictly to protect the environment.
