岷江上游生态脆弱性综合评价的集

岷江上游是四川省乃至西部地区重要的生态屏障,它生态环境的好坏危及到长江流域的生态安全,并成为区域经济社会发展的主要限制性因素.尝试应用集对分析方法对岷江上游环境脆弱性进行了评价,并与人工神经网络、投影寻踪、模糊评价比较基本一致。为该地区生态环境的进一步研究、脆弱性生态环境的恢复重建提供了科学依据。

Set-Pair Analysis of Comprehensive Evaluation of Ecological Fragility in the Upper Reaches of Min River

The upper reaches of the Min River are the typical fragile areas in the west of China,and the eco environment fragility of the area has serious effects on the implementation of the sustainable development strategy in the west of China and becomes the main restraint for the regional social economic development.In this paper,method of set pair analysis(SPA) was attempted to evaluate the regional ecological fragility in the upper reaches of the Min River.The result accords to the evaluation results of Artificial Neural Network,Projection Pursuit,and Fuzzy Judgement.It puts forward support for the regional ecological environment study and ecological restoring and rehabilitating of the fragile ecological environment in the upper reaches of the Min River.
