摘　　要：本文以清江源头为研究对象,利用室内碘量法实验获得针对清江源头附近的Streeter-Phelps模型的耗氧系数以及复氧系数,得到清江源头附近河段的氧垂曲线,根据曲线求得极限溶解氧、极限氧亏、极限距离,预测河水含氧量的变化。This paper discusses Qingjiang River source for the study based on lab-iodometric method experiment for Qingjiang River near the source of the Streeter-Phelps model of oxygen utilization coefficient and reaeration coefficient obtained catenary Qingjiang River near the source of oxygen, according to the curve to obtain limits dissolved oxygen, oxygen defieient, limits the distance predicted changes in water oxygen levels.

关 键 词：清江源头 Streeter-Phelps模型 耗氧系数 氧垂曲线
