Study On Classification And Division Of Land Renovation In

Land remediation is an important guarantee of using land resources rationally. At present, land remediation from an isolated, scattered plots of land remediation projects to comprehensive remediation of land change in the range, and focus on rural land remediation change, renovation to urban rural combination remediation, the formation of a new pattern of global plan, global remediation for all areas. After the international financial crisis, we have to continue to expand domestic demand, promoting the development of urbanization further, which resulting in shortage of land resources, a fragile ecological environment and other issues. Rational use of land resources is facing substantial challenges, land remediation is facing new development opportunities. Thus, land remediation partition become an important part of the land reclamation planning. The purpose of land remediation partition is confirm the development direction and emphasis of land remediation in different areas, and different regions using different methods, and promote the land remediation development of all regions. Land remediation function partition major consideration on the basis of comprehensive partition, which combined with the relevant planning and theories to clear the direction of land remediation.This paper introduces the principles and method of land remediation partition, according to the topography, climate, hydrology and other natural conditions of Lijiang City and differences in the land use spatial layout, the essay establish a land remediation partition index systems that make up of natural elements, land use and other indicators using GIS technology and fuzzy cluster analysis.Meanwhile, in order to effectively solve the problem of area delineation in land remediation, through the study of fuzzy mathematics and luster analysis, the fuzzy cluster analysis based on the conduction of the above two method are proposed, and elaborates the main steps of the method and calculation process. Using this method, the land remediation area of Lijiang City is divided into four categories, and the analysis result is consistent with the actual situation. According to the results, each region presented a different direction and focus remediation.
