摘 要: | 采用平面二维水库水质数值模型与综合因子评价相结合的方法,对丹江口水库现状和南水北调工程实施后的水库富营养化水平进行了预测与评价.结果表明,南水北调工程实施后,总体上水库水质为中-中-富营养水平,营养状况较工程实施前好.但局部库湾水流流速减缓,水体趋向富营养化.

Study of effects of middle route of China's South-to-North Water Transfer Project on eutrophication in Danjiangkou Reservoir |

Abstract: | Danjiangkou Reservoir is the headwater of the middle route of China's South-to-North Water Transfer Project(MR-SNWTP).It is important to take attention on the research on the eutrophication of Danjiangkou reservoir.The factors comprehensive evaluation method is used to evaluate the eutrophication of Danjiangkou Reservoir during the 2004.Then the 2-D water quality numerical model is applied to predict and evaluate the eutrophication of Danjiangkou Reservoir after the MR-SNWTP was carried on.The result shows that,after MR-SNWTP,the water quality is basically from mesotrophic to mesotrophic-eutrophic;it is better than that before implementation of the Transfer Project.However,due to the slowdown of the water flow in part of the reservoir,eutrophication is expected. |
