摘　　要：伽师县位于喀什噶尔河流域下游,水资源严重短缺,为保障县域经济社会发展,长期超采地下水,已造成区域地下水水位逐年下降。为研究伽师县绿洲平原区的地下水资源情况,本文构建了三维地下水流模型,并借助地下水模拟软件,构建了区域地下水流及溶质运移数值模型。通过对模型进行识别、验证和预报,当维持现状承压水水位不变,控制潜水水位维持在适宜水深6.0m时,2040年末伽师县地下水可开采量为5.59亿m^(3),其中矿化度小于2g/L的可开采量为1.46亿m^(3),大于2g/L的可开采量为4.13亿m^(3)。研究结果可为今后伽师县合理开采地下水提供重要的参考依据。Jiashi County is located in the downstream of the Kashgar River Basin,where water resources are severely scarce.To support the county’s economic and social development,groundwater has been over-extracted for a long time,resulting in a gradual decline in the regional groundwater levels.To study the groundwater resources in the oasis plain area of Jiashi County,a three-dimensional groundwater flow model was developed in this paper.Using groundwater simulation software,a numerical model for regional groundwater flow and solute transport was established.Through model calibration,validation,and forecasting,the results indicate that if the current confined aquifer water level remains unchanged and the unconfined water level is maintained at an appropriate depth of 6.0 meters,the exploitable groundwater volume in Jiashi County by the end of 2040 will be 559 million cubic meters.Among this,the exploitable groundwater with a mineralization of less than 2g/L is 146 million cubic meters,and that with a mineralization greater than 2g/L is 413 million cubic meters.The findings provide important reference for the rational extraction of groundwater in Jiashi County in the future.
