Analysis Land Consolidation Based On Evaluation Of Ecological Sensitivity

With the rapid development of the pace of city construction and expanding the scale of the industry in China, the farmland occupied by non-agricultural construction land and returning farmland to forest and grass have become increasingly prominent in the land supply and demand. The conversion of cropland to forest, which result in the decreasing of Chinese quantity cultivated land. China is facing with food safety problem. In order to maintain the balance of total cultivated land, increase the cultivated area, the government promote land consolidation project.The study of land remediation in China compared with western developed countries is still in the initial stage. The research theory system is still not perfect and land consolidation disorder cause ecological environment problems. Pay more attention to the economic benefits, ignoring the protection of the ecological environment, which contrary to the original intention of land remediation; The unreasonable land leveling destroy the topsoil, which result in the decreased of soil texture; The government blindly pursuit of adjustment of land use structure and standardization construction, which destroy the local ecological landscape pattern. So, we should strengthen research on "the ecological land remediation " to ensure the orderly conduct of land remediation, through land remediation to improve production conditions, improve the ecological environment. The land remediation research mainly includes: the research from the perspective of ecological of land remediation,the ecological effect evaluation of land consolidation, the ecological land evaluation research. Our country have been very mature on the study of the individual land consolidation, but the research on the comprehensive land remediation is still in the process of exploration and have less research achievements.This artical mainly take the rural land remediation in the Fukang City as the research object. First of all, according to the ecological conditions of the Fukang City, establish the evaluation index system of ecological sensitivity. Secondly, according to the comprehensive land use planning, determine the direction and goal of land remediation. Finally, the evaluation index system of ecological sensitivity as compared sequence, the ecological sensitivity evaluation standard index as the reference sequence, use the grey relation projection method to analysis the ecological sensitivity evaluation of sample points. According to the ecological sensitivity evaluation results, determine the land remediation mode.The results of the study show: the evaluation of ecological sensitivity: the Northern desert area of the soil sensitive degree and the sensitive degree of habitat is high, the Central plains area of ecological landscape sensitivity is high, the Middle alluvial fan edge mining area of the ecological sensitive degree and the land use types is high, the Southern mountain forest industrial and mining areas of the soil ecological sensitive degree is high; The comprehensive evaluation of ecological sensitivity: the Central alluvial plain agricultural areas <the Southern mountainous areas< central alluvial fan margin mining area <the North desert region;According to the ecological sensitivity of the Fukang City, summarizes eight kinds of land remediation type; According to the comprehensive evaluation of ecological sensitivity of the Fukang City, summarizes the four kinds of land remediation pattern;...
