蔷薇河生态系统健康状况评价研究

Assessment of Ecosystem Health of Qiangwei River

本文采用多指标评价法对蔷薇河进行生态系统健康评价,并将评价结果分为"病态、不健康、亚健康、健康、很健康"5个等级,构建了单一目标层、5个准则层和16个具体指标的健康河流评价体系,并借助于层次分析法建立评价模型得出研究成果。结果表明,蔷薇河生态系统健康评价综合指数为3.02,即蔷薇河处于健康状态,但已接近亚健康状态。此评价方法可为同类其它河流开展生态系统健康评价提供参考。

In order to fully understand ecosystem health of Qiangwei River, which is the only drinking water resource in Lianyungang, according to the concept of river ecosystem health, and consider the pros and cons of different evaluation methods, finally uses the multi-index evaluation method, and puts the evaluation results into five levles, sick, unhealth, sub-health, health and good health, constructs the river health evaluation system for a single target layer, five layers and sixteen indexes, and gets research results based on AHP. The results show that the ecosystem health score of qiangwei river is 3.02, in state of health, but very close to the state of sub-health. The evaluation method of this article can use on other similar rivers to develop ecosystem health assessment.
