摘　　要：民勤绿洲是河西走廊石羊河流域下游将巴丹吉林沙漠和腾格里沙漠分割的一块绿洲,对于这两大沙漠的合拢有着极其重要的意义,也对河西走廊的生态保障有着不凡的作用。本文基于GIS平台,利用石羊河流域智慧水资源管理平台采集的数据,分析了民勤盆地地下水位年内、年际变化特征和地下水位埋深的空间分布规律。结果表明,近5年内民勤盆地地下水位年内变化波动较大,年际变化相对平稳,处于回升状态,平均回升0.33 m。当地管理部门应继续合理规划水资源配比,以实现水资源的可持续发展。Minqin Oasis is an oasis that separates Badain Jaran Desert and Tengger Desert in the lower reaches of Hexi Corridor Shiyang River Basin.It is of great significance for the convergence of the two deserts,and also plays an extraordinary role in the ecological protection of Hexi Corridor.This article was based on the GIS platform and uses data collected by the Smart Water Resource Management Platform of the Shiyang River Basin to analyze the characteristics of annual and interannual changes in groundwater level and the spatial distribution pattern of groundwater depth in the Minqin Basin.The results show that the groundwater level in the Minqin Basin has fluctuated significantly within the past five years,with relatively stable interannual changes and a rebound state,with an average recovery of 0.33 m.Local management departments should continue to plan water resource allocation reasonably to achieve sustainable development of water resources.
