Research on Evaluation of Ecological Security in Shanghai City Based on Subjective and Objective weighting Method

摘要：

According to the latest statistical data from the Shanghai Statistical Yearbook-2010, 3 layers and 21 indicators of ecological safety assessment evaluation model were constructed. Subjective and objective weighting method which included the Entropy and AHP to evaluate the 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 corresponding countermeasures which could improve the ecological security in Shanghai city were given.
