| 摘 要： | 为了给调水工程运行调度及其环境影响评价提供科学依据,探讨了跨流域调水工程对流域水环境的影响作用.采用一维模型对引沁入汾工程调水前后的水质和水环境容量进行了模拟计算,进而评价调水对汾河下游段水环境的影响.研究结果表明,调水沿线各水库的水质能够满足供水需要,调水后汾河下游段的COD和NH3-N水环境容量分别比调水前增大了30.50%和31.88%.

| Abstract: | The influence of the engineering of trans-basin water transfer on basin water environment was studied for providing the scientific basis to the project operation and environment effect evaluation.Based on the analysis of the water quality change between two basins,a one-dimensional numerical model was set up to simulate water quality and water environment capacity before and after the engineering of transfering water from Qinhe River to Fenhe River,then the effect on water environment of the lower reach of Fenhe River from transfering water was evaluated.The result shows that the water quantity and quality could meet the demands along the routines,and the COD and NH3-N environment capacity in the downstream areas of Fenhe River has an increase of 30.50% and 31.88% respectively. |
