摘要
水质标识指数(WQI)能够系统、客观的评价水体的水环境类别、受污染程度等信息,根据单因子水质标识指数(P)创建的综合水质标识指数(WQI)可以全面评价水体的总体水质情况。为全面研究永定河石景山段各不同断面的水环境质量,选取永定河流域3个断面,按照2013—2016年的水断面监测数据,以综合水质标识指数计算各断面污染因子,并详细论述了永定河石景山段水质变化情况。
The water quality identification index （WQI） can systematically evaluate the water environment category and pollution degree of the water body. The comprehensive water quality index （WQI） created by the single factor water quality index （P） can comprehensively evaluate the water body Water quality situation. In order to comprehensively study the water quality of different sections of Shijingshan section of Yongding River, three sections of Yongding River Basin were selected. According to the data of water cross-section monitoring in 2013-2016, the pollution factors were calculated by comprehensive water quality index. Water quality change in Shijingshan section of river.
