Paper Abstract

In case of Xingwen County in Yibin city, this paper the 15 single indicators of natural factor, economic factor, and social factor which affect the ecological safety of land resources were selected, constructing the index system of the ecological security evaluation of Xingwen County in Yibin city. On this basis, the analytic hierarchy process (AHP) was used to determine the weight of each index, and then to calculate the value of ecological security; and the weighting function method was used to obtain that the level of land resources ecological security in Xingwen County is "good" in 2008. Moreover, the clustering analysis method was used to analyze the 15 single indicators of land ecological security, showing that the economic factor is the main factor which affects the ecological security of land resources in Xingwen County, and the corresponding countermeasures were proposed.
