杞麓湖流域水环境承载能力分析及综合对策

Analysis of Water Environment Carrying Capacity and Comprehensive Countermeasures in the Qilu Lake Basin

为有效分析通海县水资源承载能力,采用一维模式对杞麓湖的水环境容量进行了分析,并参考了其环境监测数据。研究结果表明,尽管杞麓湖近年来营养水平有所下降,水质有所提升,但仍保持在中度-富营养化状态,生活污水和农业面源污染是其主要原因,水资源环境承载力仍处于超载状态,已无环境容量。如不加以改进,环境污染很难在短时间内消除,水环境容量在很长一段时间内保持超载状态。最后提出提升杞麓湖水资源环境承载力的对策及建议。

With the rapid social and economicdevelopment in Tonghai County,the bearing pressure of water environmental is increasing,and the restricting effect of water environment on social and economic development is also becoming more and more significant.In order to effectively analyze the carrying capacity of water resources in Tonghai County,a one-dimensional model was used to analyze the water environmental capacity of Qilu Lake,and its environmental monitoring data were also referenced.The results showed that although the nutrient level and water quality of Qilu Lake have decreased in recent years,it is still in the state of moderate-eutrophication.Domestic sewage and agricultural non-point source pollution are the main reasons,and the carrying capacity of water resources environment is still in the state of overloaded,and there is no environmental capacity at all.Without any improvement,it is difficult to eliminate the environmental pollution in a short time,and the water environmental capacity will remain overloaded for a long time.Finally,some countermeasures and suggestions were put forward to improve the water environmental carrying capacity of Qilu Lake.
