摘要
通过济南流域水生态调查,对济南全流域进行水功能分区,在此基础上利用层次分析熵值法分配水功能区权重,对济南流域水生态健康状况进行评价。评价结果显示,位于济南南部山区森林水源水生态亚区水生态状况优良;济南中心泉区水生态状况优良;位于东部平原农业生态亚区和南部丘陵-平原农业水生态亚区,主要受农业面源污染影响,水生态状况较差。
Through the water ecological survey of Ji'nan basin,the water function area of Ji'nan basin was carried out.On this basis,the water ecological function of Ji'nan basin was evaluated by the analytic hierarchy process(entropy)method.The evaluation results show that in the southern forest area ecology is excellent.The center spring area,water ecology is good.Two area ecological conditions are bad where located in the Eastern Plain Agricultural Ecology and the southern hilly Plain Agricultural Water Ecology,mainly affected by the impact of agriculturalnon-point source pollution.
