摘　　要：近年来,黑河中游灌溉面积的扩张变化,使地下水位持续下降,影响了黑河中游地下水系统的补排关系,对地下水资源时空变异性产生深远的影响;运用统计方法研究了地下水埋深的空间变异特征,分析了中游土地利用变化影响下地下水位时空变异性的特性及地下水对灌溉面积变化的响应。The groundwater level is closely related with the spatial and temporal change of land use in the middle reaches of the Heihe River .The groundwater level has been declining because the irrigation areas have been expanded in recently years ,which has signifi‐cantly effected on the groundwater resources and the relationship between recharge and discharge of the groundwater system in Heihe River .This paper studied the spatial variation of the groundwater with the land use change and its responses to the change of irriga‐tion areas in the middle reaches of the Heihe River by a statistical method .
