摘　　要：对汾河太原段水质监测数据的统计分析结果表明,汾河太原段的水质污染严重,在其9个监测断面中,小店桥和温南社断面的水质污染最为严重,主要污染物为5日生化需氧量、氨氮和高锰酸盐;采用综合指数法对2007年汾河太原段枯水期、平水期及丰水期内的水质变化情况进行了分析,表明汾河太原段上游段水质最好,中游段水质次之,下游段水质最差,且滩上桥、寨上水文站和温南社断面在河流解冻期时污染明显加重;在此基础上,针对各河段的水污染问题提出了相应的建议。This paper makes statistical analysis on the water quality monitoring data of Fenhe River＇ s Taiyuan section, and points out that the water pollution of Fenhe River＇s Taiyuan section is very serious, the water pollution of Xiaodian Bridge section and Wennanshe section, the two of those nine monitoring sections, is the most serious, and the main pollutants are the BODS, NH4-N and Permanganate; and in addition, analyzes the changes of the water quality of Fenhe River＇ s Taiyuan section in 2007 during the low water period, normal-water period and High flow period, and the results of which indicate that the water quality of the upper reaches of Fenhe River＇ s Taiyuan section is the best, the water quality of the middle reaches of Fenhe River＇s Taiyuan section takes second place, and the water quality of the lower reaches of Fenhe River＇s Taiyuan section is the poorest; and the water quality of Tanshang Bridge section, Zhaishang Hydrometric Station section and Wennanshe section becomes worse in the molting period; and based on this, puts forward some corresnponding suggestions in the light of the water pollution of each section.
