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
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。
