基于PSR模型,结合长沙市的具体情况构建生态安全评价的指标体系,同时利用层次分析法结合模糊数学方法对研究区的生态安全进行评价分析.结果表明:2001~2008年长沙市生态安全等价值由3.00下降到2.48,生态环境逐步步入良性循环.评价结果与长沙市近8年的实际情况相吻合,表明该分析方法具有一定的科学性.
基于PSR模型,結閤長沙市的具體情況構建生態安全評價的指標體繫,同時利用層次分析法結閤模糊數學方法對研究區的生態安全進行評價分析.結果錶明:2001~2008年長沙市生態安全等價值由3.00下降到2.48,生態環境逐步步入良性循環.評價結果與長沙市近8年的實際情況相吻閤,錶明該分析方法具有一定的科學性.

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 analysis method was scientific and reasonable.
