太湖西苕溪流域环境流量评价分析
Environmental flow assessment in Xitiaoxi catchment of the Taihu Basin
摘要
Abstract
Estimation of environmental flow provides an effective tool to improve the water environment and optimize the allocation of water resources under the background of the contradiction of water withdrawal and serious river pollution in wet areas,the case study area was chosen in the Xitiaoxi River,Taihu Basin. Dif⁃fering from ecological water demand, which is focused on vegetation, soil, rainfall and runoff in the rivers and in the process of biological research in the natural state watershed, the study set the evaluation criteri⁃on by making quantitative analysis in the combination of quality and quantity from the perspective of river health strongly interfered by human activities, using objective entropy weight to amend comprehensive water quality identification index,combing water use efficiency and discharge concentration of waste water. The re⁃sults show that the environmental flow of Xixi, Nanxi and Longwangxi streams all meet the standard except Huxi and the main stream, while the water quality as the precedence constraints, its pollutant index’s weight may play a key role in the whole process of evaluation and Xixi’s change has proved that. Com⁃pared with the method of mean value, the revised method can effectively avoid the worst factor’s influ⁃ence,and provide a new way for environmental flow evaluation under quality and quantity in water-rich ar⁃eas.关键词
