摘　　要：以研究区近20年观测井地下水埋深观测数据分析了石羊河下游民勤绿洲地下水位的年际变化、季节变化动态及空间分布特征,结果表明:研究区地下水埋深年际变化以严格统计直线型加深;季节变化具有春秋季变化剧烈,地下水埋深剧烈加深和快速恢复,夏季地下水埋深加深达顶峰,冬季地下水缓慢恢复的特点;空间变化具有沿绿洲到荒漠方向距离绿洲中心越远地下水埋深越浅,沿石羊河古河道越到下游,地下水埋深越浅的特点。Analyzed change of the ground water level in Minqin Oasis of Shiyang River lower reaches by recent 20 years data in facet of annual change, seasonal change and spacial-temperal character. The results showed that the ground water level went down annually by strict statistics liner mode in the area; which went down in spring and went up greatly in autumn, showed minimum in summer, when it comes to winter, the ground water level began to comeback slowly in seasonal change. The ground water became lower from oasis center to desert and from Shiyang River upper reaches to lower reaches.
