与三座峡水库的被坝所围住的水，海藻的花蕾在一些支流被发现了。在这研究，根据在一条河类型水库支流的超营养作用机制的理论分析，一个一个维的超营养作用模型为水藻的主要生长率上的水动力学条件的三座峡水库，和影响的 Xiangxi 河支流被开发被调查。而且，水力的变量的数字预言和超营养作用因素例如 TP 的集中分发， TN，和 Chl -- 一在里面空间、时间的域，被执行。TP， TN，和 Chl 的计算结果的比较 -- 一沿着在有试验性的数据的 2005 的春天的河的集中表明模型的有效性。在计算结果和 TP 和 TN 集中的试验性的数据之间的协议比 Chl 的在那些之间的协议好 -- 集中。模仿的结果也证明 Chl -- 集中下游地在在上游的支流比那高得多，它潜在地在这个区域显示水藻的爆发。因此，这研究提供精确地在河类型水库和他们的支流预言超营养作用的状态的一个可行方法。

英文摘要：

With the impoundment of the Three Gorges Reservoir, algal blooms have been found in some tributaries. In this study, according to the theoretical analysis of the eutrophication mechanism in a river-type reservoir tributary, a one-dimensional eutrophication model was developed for the Xiangxi River tributary of the Three Gorges Reservoir, and the influence of hydrodynamic conditions on the primary growth rate of algae was investigated. Furthermore, numerical predictions of hydraulic variables and eutrophication factors, such as the concentration distribution of TP, TN, and Chl-a in the spatial and temporal domains, were carried out. Comparison of computation results of TP, TN, and Chl-a concentrations along the river in the spring of 2005 with experimental data demonstrates the validity of the model. The agreement between the computation results and the experimental data of TP and TN concentrations is better than the agreement between those of Chl-a concentration. The simulated results also show that the Chl-a concentration downstream is much higher than that in the upstream tributary, which potentially indicates the outbreak of algae in this area. Therefore, this study provides a feasible method of accurately predicting the state of eutrophication in river-type reservoirs and their tributaries.
