以三峡水库万州段主要支流回水区的水质作为研究目标，逐月监测瀼渡河、石桥河、五桥河和苎溪河4条支流回水区从2011年1月到2013年12月的高锰酸盐指数、总氮、总磷、叶绿素 a、透明度等5项指标，采用综合营养状态指数法进行评价。通过折线图、箱线图及Mann-Kendall法分析了各条支流回水区的富营养化时空分布，结果显示流经区域以农业为主的瀼渡河、石桥河、五桥河3条河流存在夏季季节性的富营养化，而流经区域以城市为主的苎溪河则常年处于富营养化状态。因此，未来对于以三峡水库万州段支流回水区的富营养化防治工作应同时考虑气候因素和人类活动因素的影响。

This paper takes the water quality of the main tributaries of the backwater areas in Wanzhou section in Three Gorges Reservoir as the research target. The soil across the river, river stone, five bridges over the river and tributaries Limonene River backwater area 4 are monthly monitored from January 2011 to December 2013 in terms of 5 permanganate indexes:total nitrogen, total phosphorus, chlorophyll a, transparency, etc. and evaluated the related results with trophic state index method. Through the line chart, box plot and Mann-Kendall method it analyzes the spatial and temporal distribution of the tributaries eutrophication backwater area. The results showed that flows through the area predominantly agricultural soil river, river stone, and five bridges over the river three rivers have summer seasonal eutrophication, while Limonene River passing through the urban area constantly in the perennial state of eutrophication. Therefore, in the future, to prevent and control Eutrophication in tributary backwater areas in Wanzhou section in Three Gorges Reservoir, climatic factors and human activities should also be considered.
