摘要

As an important water source of Weifang ,Shandong Province,Xiashan reservoir has great significance for the development of society,economy and environment.In this paper,we use a single standard pollution index method based on water monitoring data from 2009 to 2011 to assess and analyse the quality of the Xiashan reservoir .The results show that the main water quality of Xiashan reservoir is classⅢ.But there is still a certain gap to achieve class Ⅱthat first-grade protection zone of water source requires .The main pollutant is COD, TP.%　　峡山水库作为山东省潍坊市重要水源地，对潍坊市社会、经济和环境的谐调发展具有重要的意义。本文根据2009-2011年水质监测资料利用单项标准污染指数法对峡山水库的水质进行了评价与分析。结果表明：峡山水库水质以Ⅲ类水质为主，距离水源地一级保护区要求达到的Ⅱ类标准仍有一定的差距，主要的污染因子为COD、TP。
