基于生态保护目标的乌梁素海生态需水研究
The research of ecological water demand of Ulansuhai Nur based on the ecological protection targets
摘要
Abstract
This paper considers the existing ecological problem and actual situation of Ulansuhai Nur,and establishes its ecological protection targets,i.e.storage capacity of 240-943 million m^3,water stage of 1018.35-1020m,and water quality of class IV.With these targets and the water balance method,we conclude that a water balance of this lake requires the draining system to provide it a long-term water supply of 5.48×10^8m^3/a.The lake′s water demand by its ecological environments under class IV quality is a primary representation of its ecological water demand.Using the environmental diluting method of water demand,we develops an ecological water demand model for the lake,and its calculations of the lake′s ecological demands in 1,5 and 10 years in the existing conditions are 973,462 and 438 million m^3 respectively.These demands could be reduced through pollution control,for instance,reduced to 678,239 and 225 million m^3 if the pollutant is cut down by 30%,and further to 607,176 and 153 million m^3 if cut down by 40%.The presented results are essential to the planning of ecological restoration in Ulansuhai Nur.关键词
