| Abstract: | According to the specific statement of Changsha,this research constructed the indices system based on PSR model,and analyzed the ecological security of the area using AHP combined with fuzzy comprehensive evaluation.The results indicated that,in 2001-2008,the value of ecological safety etc.decreased from 3.00 to 2.48 in Changsha,and ecological environment gradually entered benign circulation.Evaluation results matched with the actual situation in nearly eight years of Changsha,which indicated that this anal... |
