- Abstract:
-
The evaluation system of ecological security of Chongqing City was built according to the model of Pressure-State-Response, and the model of coupling of the entropy weight and attribute distinction theory was applied to comprehensively assess the nine districts of Chongqing City. The evaluation showed that the ecological security of Shapingba, Yubei District and Banan District in Chongqing had shown some improvement, evolving from low ecological security grade to the high grade, and the score of ecological security presented an increase trend. But the ecological security change trend and score of Yuzhong, Jiangbei and Jiulongpo Districts showed an opposite situation. The ecological security situation of Dadoukou, Nanyan and Beibei Districts fluctuated, and the development trend was uncertainty. Attribute distinction model has the advantage of simple calculation, high precision, and more effective identification as well as comprehensive analysis compared with the others models, which is regarded as a new way for ecological security evaluation.
