摘　　要：基于黄壁庄水库水体受污染的现状,以真实掌握水库水质为目的,客观合理的水库水质评价已迫在眉睫。以黄壁庄水库为研究区,采用改进的内梅罗指数法对水库进行水质评价。结果表明,在丰水期,黄壁庄水库为Ⅰ类水质;平水期为Ⅲ类、Ⅳ类水质;枯水期水质较差,为Ⅲ类、Ⅴ类水质;此结果与黄壁庄水库实际情况相符。改进的内梅罗指数法相比传统的内梅罗指数法,对各污染指标进行主客观赋权,并对最大污染指数进行修正,更能真实反映水库水体水质,结果更为合理,具有一定的科学性,操作性更强,可为改善水体水质提供技术依据。In view of the state quo of water pollution in Huangbizhuang Reservoir,it is urgent to evaluate the water quality of Huangbizhuang Reservoir objectively and reasonably for the purpose of truly grasping the water quality of the reservoir.By taking Huangbizhuang Reservoir as the research area,the water quality of the reservoir was evaluated by the improved Nemerow index method.The results show that the water quality of Huangbizhuang Reservoir is Class I in the high water period,ClassⅢand Class IV in the plain water period,Class IV and Class V in the dry water period.This result is consistent with the actual situation of Huangbizhuang Reservoir.Compared with the traditional Nemerow index method,the improved Nemerow index method gives subjective and objective weight to each pollution index and corrects the maximum pollution index,which can reflect the water quality of the reservoir more real.The result is more reasonable,scientific and operational Therefore,the method can provide technical basis for improving water quality.
