基于AHP法的模糊综合模型在流域生态健康评价中的应用

Application of AHP Based Fuzzy Comprehensive Evaluation Model in Assessment of River Basin Ecological Environment Health

流域生态环境健康评价是流域内水资源合理开发利用、经济社会可持续发展和生态环境保护的重要依据^([1]),也是流域生态健康状况的一种系统诊断方式。在确定疏勒河流域生态健康评价指标的基础上,采用层次分析法研究各指标,应用模糊综合评价法对流域生态系统健康程度进行综合评价。疏勒河流域健康程度隶属度为0.4219,属于亚健康(0.4~0.6)状态,依据评价结果,分析该流域生态环境存在的主要问题,并提出建议。

The river basin ecological environment health assessment is the important basis for reasonable water exploitation,sustainable development in economic,social and ecological environment protection,there are also the system diagnostic methods for river area ecological health status.On the basis of ecological environment health assessment for the Shulehe River Basin, this paper used the analytic hierarchy process to research each assessment index,and usedfuzzy comprehensive evaluation method to assess the level of river basin ecological environment health.The subjection degree is 0.4219 forhealth level ofthe Shulehe River Basin.It belongs to sub-health（0.4 ~0.6）status.According to the evaluation results, this paper made an analysis of the main problems in the ecological health of the river basin,and put forward some suggestions.
