Impact-post Assessment of Ecological-based Emergent Water Conveyance Project at Downstream the Tarim River

GE Xue-qian,WU Juan,YU Lin(College of Water Conservancy and Hydropower Engineering of HoHai University,Nanjing 210098)  
Ever since ecological water was fed to the downstream of the Tarim River,concerns have centered on how to define a rational ecological protection scope and ecological water demand for downstream ecological safety assurance system,and how to provide scientific basis through a system composed of such relative factors as river flow advance,rise of ground water level,and vegetation recovery for overall benefit assessment of downstream ecological-based emergent water conveyance project,river regulation,reasonable allocation and optimal scheduling of water resources,and ecological restoration.However,there have been just a few studies on impact-post assessment of ecological-based emergent water conveyance project at downstream the Tarim River.In view of this,this paper attempts to discuss the impact-post assessment of the said project with ecologicalbased water conveyance to the downstream of the Tarim River as the background,and aims to develop a study framework for that,offering a basis for an objective and fair assessment of the project's impacts.
