Based on the Water Quality Weekly of the surface water environment target responsibility section of Henan Province and the data of Environment Bulletin of Jiaozuo City, this study carries put the single factor evaluation and Nemerow comprehensive pollution index evaluation for 5 indexes of CODMn, BOD5, ammonia nitrogen, COD, TP of three controlled monitoring sections of Xiuwu Hydrological Station, Wenxian Sishui Station and Huojia Dongbei Station. The results show that: ①the single factor pollution index of ammonia nitrogen in the three monitoring sections exceeded the standard during the period of 2003~2014, but the Nemero comprehensive pollution index decreased year by year. ②CODMn index and BOD5 single factor pollution index in Jiaozuo Province Control Monitoring Section exceeded the standard in 2015, ammonia nitrogen single factor pollution index exceeded the bid badly. The times of ultra standard in Huojia Dongbei Section are 3.35.%本研究以河南省地表水环境责任目标断面水质周报和焦作市环境状况公报数据为基础，对焦作市修武水文站、温县汜水滩和获嘉东碑村3个省控监测断面的高锰酸盐指数、BOD5、氨氮、COD、总磷等5项指标进行单因子和内梅罗综合污染指数评价。评价结果表明：①3个监测断面在2003~2014年间氨氮单因子污染物指数超标，但内梅罗综合污染物指数逐年下降。②2015年焦作市省控监测断面中高锰酸盐指数、BOD5单因子污染物指数超标，氨氮单因子污染物指数严重超标，其中，获嘉东碑村断面，超标倍数高达3.35倍。
