摘　　要：为了加强鄯善县地下水管理,首先需要研究地下水动力场在人为和自然因素影响下的变化趋势。根据地下水长观井监测数据和历史资料,分析了鄯善县南盆地的地下水动态特征和地下水流场的变化规律,运用GIS软件,采用空间运算和叠图等方法,计算了三个时期的地下水储变量:1959—2004年,地下水储量减少11.6×108m3;2004—2011年,减少了2.8×108m3,总计减少14.4×108m3。总结了鄯善县南盆地地下水动力系统的演化规律:20世纪60年代以前,地下水系统为脉动非稳定系统;20世纪60年代以后,为动态非稳定扩张系统。In order to strengthen the groundwater management in Shanshan ,the variation trend of the dynamic field should be studied first .The dynamic characteristics and dynamic field evolution of the groundwater in the south basin of Shanshan County were analyzed according to the data collected from monitoring wells and historical data .The decrement of the ground water resource was calculated with GIS software and by using the spatial operation method and figure overlap method .The results are as follows ：it was reduced by 11 .6 × 10^8 m3 during 1959 - 2004 ;it was reduced by 2 .8 × 10^8 m3 during 2004 - 2011 ,in total ,it was reduced by 14 .4 × 10^8 m3 .Simultaneously ,the evolution law of the groundwater in the south basin of Shanshan was revealed ：the groundwater’s dynamic field was a pulsing non-stability system before 1960’s ,and a dynamic non-stability expansion system after that .
