摘　　要：为了建立简单而又普适、通用的地表水水质评价模型,提出基于指标规范值的综合水质标识指数法,以便对水质进行合理的定量评价。该方法首先设定指标参照值和指标规范变换式和对指标数据进行规范化处理基础上,改进了传统水质标识指数评价法,采用超标法确定各指标权重,最后用各指标的单因子水质标识指数的加权和,求得基于指标规范值的综合水质标识指数,以此作为依据进行水质评价。将基于指标规范值的综合水质标识指数评价法应用于浮桥河水库水质评价,结果表明:该方法具有简单和普适、通用的特点。In order to establish simple, common and universal water quality assessment model, a method of compre- hensive water quality identification index based on normalized index values was proposed so as to make reasonable quantitative evaluation for water quality. In the basis of setting reference values and normalizing transformed forms for each index value; the traditional water quality assessment of identification index was improved, Then the weight of each index is determined by using over-standard method. Finally, the weights of single factor water quality identi- fication index are summed up to obtain the comprehensive water quality identification index for water quality assess- ment. This method was applied to the water quality assessment of Fuqiao river and the results showed that the method is simple, universal and common.
