| Popis: |
An urban eco-security evaluation system of 18 cities in Sichuan province was established by using PSR (Pressure-Status-Response) method. In this research the parameterized combination operator model which is propitious to fuzzy inversion problem was selected to evaluate over the situation from 2005-2007, using the particle swarm optimization (PSO) to optimize the parameter of parameterized combination operator. The results show that Chengdu was in a relative safe state and the other 17 cities are in critical safe; total situation of eco-security in Sichuan during 2005-2007 keeps on improving. The results gain with our method is basically consistent with the actual situation. It is seen that the urban eco-security indexes and evaluation model in our research are both feasible and efficient to solve the eco-security evaluation. |
