综合水质标识指数法及单因子水质标识指数法在2013年官厅水库水质评价中的应用

综合水质标识指数评价法和单因子水质标识指数评价法是目前运用比较多的水质评价方法,尤其两种方法结合起来能完整地表达水体的综合水质信息,计算过程简单,既可进行定性评价,也可进行定量评价。本文应用综合水质标识指数法和单因子水质标识指数法选取代表性监测项目对北京市的重要水源地——官厅水库2013年的水质监测数据进行分析,评估官厅水库水体现状,为改善水质及生态环境提供科学依据,也为在北京市地表水源地水质评价中运用此类方法提供借鉴。

Application of comprehensive water quality identification index method and single factor water quality identification index method to water quality assessment of Guanting Reservoir in 2013

Both the comprehensive water quality identification index method and the single factor water quality identification index method are the water quality assessment methods to be frequently used at present，especially，the comprehensive quality information can be completely expressed by both the methods，if they are integrated together; which can not only make qualitative assessments，but can also make the quantitative assessments with simple calculating processes. Based on selecting the representative monitoring items with the application of both the methods mentioned above，the water quality monitoring data in 2013 of Guanting Reservoir——the important water source of Beijing is analyzed herein for assessing the status of the water body in the reservoir，so as to lay a scientific basis for improving the water quality and the eco-environment therein and then provide some references for applying this kind of method to assess the surface water source in Beijing.
