摘　　要：三峡水库Ⅱ期(135 m水位)蓄水前后,成库河段的主要次级河流的常规水质整体维持稳定,但富营养化专项监测表明几条典型的次级河流的部分河段成库后藻类活动旺盛,营养状态异常,应当对三峡水库成库河段的主要次级河流的水体富营养化问题引起高度重视。Before and after the second phase of sluice of the Three - Gorges Reservoir when its water level reaches 135 m, the general quality of the water in the tributaries of the Chanriang River which empty themselves into the reservoir remains stable. Special eutrophic monitoring, however, shows that the activities of phytoplanktons in some sections of a few typical tributaries are quite heavy and trophic abnormalities occur. Therefore, the eutrophication of water in these tributaries should be given serious attention to.
