摘　　要：以乌江流域思南段为研究对象,沿途选取9个监测点,分析该区域夏季基本水化学参数TSS、TN、TP、CODMn、Chl-a的分布特征,同时分析了Chl-a与TP的相关性.结果表明：TSS含量范围0.21～0.27 g/L,TN含量范围1.33～3.87 mg/L,TP含量范围0.03～0.10 mg/L,CODMn含量范围1.02～4.32 mg/L,Chl-a含量范围0.43～13.10μg/L.叶绿素-a与TP的相关性分析表明两者呈著正相关.另从沿程分布看,各监测数据都表现出库区内较河道内高的特征.The basic hydro-chemical parameters TSS, TN, TP, CODa,, Chl-a distribution characteristic and the prelim- inary relevance of chl-a to TP in summer were analyzed by choosing nine monitoring sites of Sinan area of Wujiang river. The results show that the TSS concentration range is 0.21- 0.27 g/L, TN concentration range is 1.33- 3.87 mg/L, TP concentration range is 0.03- 0.10 mg/L, CODMn concentration range is 1.02- 4.32 mg/L, ehlorophyll-a concentration range including 0.43 - 13.10 g/L, average concentration is 4.02 g/L. The results showed that the Chl-a and TP have a significant correlation, the monitoring data in reservoir area is relatively higher than in the river along the way.
