调水对汉江中下游水质和水环境容量影响研究

Environmental Impact of South-to-North Water Transfer on the Mid-lower Reach of Han River: Modelling Prediction of Water Quality and Aquatic Environmental Capacity

南水北调中线工程拟从位于汉江上游的丹江口水库调水 ,研究采用一维圣维南非恒定流方程和一维对流扩散方程模拟预测汉江中下游干流的总体水质状况 ,对多年平均流量条件下汉江中下游的现状水环境容量及调水工程实施后的水环境容量损失进行了预测 ,为南水北调中线工程提供了科学的决策依据。

According to the planned middle route project of the SNWT, a great amount of water will be diverted to the north from Danjiangkou Reservoir in the Han River. Downstream the Reservoir is the mid-lower reach of the Han, which will be affected environmentally due to decreased runoff. This paper reported on the modeling study of the river water quality prediction and the loss of aquatic environmental capacity using 1-D hydraulic and water quality model.
