摘　　要：20 0 3年 6— 11月曾 4次对北京市城区北环水系 8个地点进行了每mL水样中细菌总数和每L水样中大肠菌群数量检测 .结果显示 ,细菌总数在 7月份出现最高峰 ,西海、后海和前海的细菌总数较多 ;大肠菌群 7和 9月份呈现高峰 ,动物园北水体中大肠菌群明显高于其他地点 .根据中华人民共和国地表水环境的质量标准 ,城区北环水系中大部分水系属于Ⅱ类 ,少数水域属于Ⅲ类和Ⅳ类水质 .因此应加强对污染源的控制 ,防止污染源向水体排放 。Investigation was done four times on the north ring water system of Beijing during June to November of 2003. Every time 15 samples were taken from different places of north ring water system, and the total bacteria (mL -1) and Coliform (L -1) were analyzed using the microbiological methods. The results indicate that the total bacteria appeared as the highest in July and the higher number of it appeared in Xihai, Houhai and Qianhai of the north ring water system. The Coliform appeared as the highest in July and November and the highest number of it appeared in the places of Zoological Garden. According to the Environmental quality Standard of Surface Water, P. R. China, the quality of most places of north ring water system belongs to the II level, and the quality of only few places belongs to Ⅲ and Ⅳ level, respectively.
