摘　　要：针对干旱内陆河绿洲灌区地下水位上升及塔里木河源流区限额供水的现实条件,本文以新疆阿瓦提绿洲灌区为研究区域,通过MODFLOW建立地下水流数值模型,模拟了现状及限额供水后的预测结果,并根据灌区的实际情况提出合理的地下水开采方案,以达到有效调控地下水位的目的。此方案下地下水开采量为1.14×108m3/a,并在全区范围内合理控制地下水位,为防治土壤盐碱化、减少无效蒸发和区域水资源的优化配置提供了有益参考。Bases on the reality of groundwater table rise and restriction water supply in Tarim river basin, a case as Await oasis irrigation area in Xinjiang. Through the establishment of MODFLOW groundwater flow numerical model to simulate the result of the actuality situation and limitation water supply. As a result, confirm a reasonable groundwater exploitation quantity in different situation to achieve effective control water table. The quantity of groundwater exploitation is 1.14×10^8m3/a under this situation and within the framework of reasonable control of the water table in Awati region, soil salinization for the prevention and treatment to reduce the null void evaporation and the optimal allocation of water resources in the region, and to provide a useful reference for inland areas.
