摘要
Abstract
On the basis of statistical data and P-S-R framework to establish the ecological security e-valuation index system,this paper has calculated the land ecological security conditions in various coun-ties by using mutation progression method. The results are as follows:Most regions of Xiangxi,which is lo-cated in the area with fragile ecological environment,are in the state of unsafety and less safety;Jishou and Fenghuang are in unsafe condition;Luxi,Huayuan,Baojing,Guzhang,Yongshun and Longshan are in the state of unsafety. According to the analysis of problems about land ecological security,the authors have offering some corresponding suggestion with purpose of realizing the sustainable use of land resources in the fragile ecological environment areas. 3figs. ,4tabs. ,25refs.关键词
