| Abstract: | Based on fuzzy matter-element analysis theory,a fuzzy matter element model, which is combination with entropy method and Euclid closeness degree,is used for the urban eco-security evaluation;and the procedure for calculation is presented in detail.The model is applied to assess the urban eco-security of Zhengzhou and the result is compared with other methods.It indicates that the fuzzy matter element method is simple,reasonable,and practical in urban ecological security evaluation. |
