以汾河太原段为研究对象,采用稀释接种法对2003年—2008年太原段9个断面的5日生化需氧量（BOD5）进行监测,得到同一断面不同月份的BOD5值。发现,BOD5峰值出现的月份不同;在同一时间不同断面的BOD5值不同,其水质上游段较好,中游段次之,下游段较差。同时,根据年平均BOD5值对以上断面进行水质功能划分。其中,水库出口和上兰的水质均达到Ⅰ、Ⅱ类,胜利桥和迎泽桥的水质为Ⅴ类,其余断面水质都是劣Ⅴ类。表明,汾河太原段污染较严重,特别是在出现BOD5值最高峰的月份,应重点监测以及采取相应的措施。
以汾河太原段為研究對象,採用稀釋接種法對2003年—2008年太原段9箇斷麵的5日生化需氧量（BOD5）進行鑑測,得到同一斷麵不同月份的BOD5值。髮現,BOD5峰值齣現的月份不同;在同一時間不同斷麵的BOD5值不同,其水質上遊段較好,中遊段次之,下遊段較差。同時,根據年平均BOD5值對以上斷麵進行水質功能劃分。其中,水庫齣口和上蘭的水質均達到Ⅰ、Ⅱ類,勝利橋和迎澤橋的水質為Ⅴ類,其餘斷麵水質都是劣Ⅴ類。錶明,汾河太原段汙染較嚴重,特彆是在齣現BOD5值最高峰的月份,應重點鑑測以及採取相應的措施。

In this paper,from 2003 to 2008 BOD5 values of surface water of nine different sections in Fen River of Taiyuan region had been monitored.It was concluded that BOD5 values of the same section in different months had great differences and the maximum BOD5 value of every year appeared in different months.The BOD5 values in same time at different sections were also different.The water quality of upstream was better than others,that of middle stream took second place and that of downstream was worst.According to the average BOD5 value of every year,the function of water had been determined.The BOD5 values in sections of Reservoir Exports and Shanglan were lower than BOD5 standard value of Ⅱ,that of Shengli bridge and Yingze bridge was lower than BOD5 standard value of Ⅴ,that of other sections was higher than BOD5 standard value of Ⅴ.The surface water in Fen River of Taiyuan region had been polluted incoordinately in recent years and should be monitored especially in the month of maximum BOD5 value to prevent it from much more serious polluted.
