摘　　要：本文将层次分析法和熵权法组合赋权的综合水质标识指数法用于碧流河水库的水质评价,并将改进前后的评价结果进行了对比。结果表明:利用等权重的综合水质标识指数法评价碧流河水库大堡和钟岭两个断面水质达到国家地表水Ⅲ类标准,桂云花水质达到地表水Ⅱ类标准。而用组合赋权的综合水质标识指数法评价三个断面的水质均为Ⅲ类。改进权重的评价过程考虑了总氮严重超标的因素,比改进之前更加客观合理。评价结果为该水库管理水环境和治理水污染提供参照。In this paper, The synthetical water quality identification index method of combination weight by analytic hierarchy process and entropy weight method was used in the water quality assessment of Biliuhe Reservoir, and the assessment results before and after empowerment were compared. The results show that the water quality of the sections of Dabao and Zhongling reaches the national class Ⅲ standard of surface water and the water quality of Guiyunhua reaches class Ⅱ standard using the synthetical water quality identification index method of a same weight. However, the water quality of the three sections is class Ⅲ using the method of empowerment. Because the factor of total nitrogen seriously exceeding the standard is considered, the improved assessment method is more objective and reasonable than the traditional one, and the assessment results can be taken as references for water environment management and water pollution control of the reservoir.
