摘要
根据《上海统计年鉴-2010》最新统计数据,通过构建3个准则层和21个评价指标的生态安全评价模型,采用熵值法和层次分析法相结合的主客观赋权法,计算出上海市近10年来的生态安全指数,同时进行动态分析。结果表明,上海生态安全状况总体呈逐年上升趋势。最后,对进一步提高上海市生态安全水平提出相应对策。
According to the latest statistical data from Shanghai Statistical Yearbook-2010,3 layers and 21 indicators of ecological safety assessment evaluation model were constructed.Subjective and objective weighting method which included entropy method and AHP were adopted to evaluate ecological security index of Shanghai during last decade.Meanwhile dynamic analysis was adopted.The results showed that the ecological security index of Shanghai had increased year after year.The countermeasures which could improve the ecological security in Shanghai City were given.
