我国河流单因子水质标识指数评价方法研究

Single Factor Water Quality Identification Index for Environmental Quality Assessment of Surface Water

出一个全新的河流单因子水质评价指数———单因子水质标识指数 .单因子水质标识指数可以完整标识水质评价指标的类别、水质数据、功能区目标值等重要信息 ,既能按国家标准类别定性评价 ,又能根据标识指数进行水质数据的分析 ;既可以比较分析同一类水质指标在同一级别中的差异 ,也可以在不同类别水质指标中比较分析水质的污染程度 .

The single factor water quality identification index,which is a new tool for single water quality factor assessment of surface water,is presented.The characteristics of single factor water quality identification index are:Firstly,it can completely identify the important information including water quality classification of assessed factors,water quality monitoring data,planned water quality classification of water environment function area;secondly,it can evaluate the selected factors qualitatively by national water quality standards,and water quality monitoring data;thirdly,it can be used to compare water quality of the same assessed factors in the same classification and water quality of different assessed factors.
