the City of Anshan is one of the key areas of Taizi River Basin in terms of water quality monitoring.This study reports the results from a lab analysis on major water quality indicators such as COD, BOD etc., for water samples collected in Niuzhuang water quality control section of Haicheng River in Taizi River Basin of Anshan during the period from 2011 to 2015.The results showed that although some indicators of Haicheng River could meet relevant water quality standards, water quality of Haicheng River was in total fluctuated in a large scale and pollution was generally serious.More serious pollution can be observed during dry season, which may impose effects on the other seasons.%鞍山市是辽宁省太子河流域水质监控的重点区域之一.本研究中采集了2011 年到2015年的太子河流域鞍山段海城河流域牛庄监控断面的水质样品,对化学需氧量、生化需氧量等水质指标进行测试分析.实验结果表明:海城河流域的相关实验监测值虽可以达到一定的水质标准,但水质波动很大,污染相对较为严重.而且在各个水期分析当中,枯水期的污染相对较为严重,而且很有可能会对其他水期造成一定的污染.
