摘　　要：本文以叶尔羌河流域为研究对象,基于WEAP模型对流域现状需水量进行了模拟。结果表明:干旱年,研究区总需水量为60.71亿m^3,缺水10.597亿m^3;重度干旱年,总需水量为56.559亿m^3,缺水14.749亿m^3;极端干旱年,总需水量为55.164亿m^3,缺水16.143亿m^3。造成缺水的主要原因是:河川径流年内年际分配不均,缺乏山区控制性水利工程,平原水库蒸发,渗漏损失较大及河道沿程损失大。研究结果为该流域水资源的可持续利用提供了科学依据。In the paper,Yarkant River basin is adopted as a research object for simulating river basin current(2012)water demand on the basis of WEAP model.The results show that total water demand in the study area is6.071billion m3during drought year,and water deficiency is1.0597billion m3.Total water demand was5.6559billion m3in the severe drought year,and water deficiency is1.4749billion m3.Total water demand is5.516.4billion m3in extreme drought year,and water deficiency is1.6143billion m3.The main reason for the water shortage is shown as follows:uneven interannual distribution in the river runoff year,no controllable water conservancy project in mountainous area,evaporation of plain reservoir,great leakage loss and large loss along the river.The research results provide scientific basis for sustainable utilization of water resources in the river basin.
