摘　　要：石羊河流域位于甘肃省河西走廊东部,该流域地下水开采所引发的一系列生态环境问题已成为制约当地社会经济可持续发展的重要瓶颈,对该流域地下水进行研究,不仅在地下水资源应用研究方面具有科研意义,而且在流域地下水资源的合理利用和流域生态恢复建设方面具有实践和指导意义。本文通过利用石羊河流域武威盆地,民勤盆地,昌宁盆地,南湖等地下水埋深长期观测资料和定期地下水位调查点调查资料,对地下水埋深的时空变化特征进行分析,结果显示,该流域地下水埋深从上世纪80年代开始呈下降趋势,上世纪90年代埋深下降最大,2000年后地下水位开始回升,地下水埋深年际变化,季节性明显。1987~2006年地下水埋深空间变化强烈。掌握研究区地下水埋深的时空变化规律,可为生态水量调度方案的编制提供重要的数据支持。Shiyang River Basin is located in the east of Hexi corridor in Gansu province,a series of ecological environment problems caused by the basin groundwater mining has become an important bottleneck which restrict the sustainable development of local social economy,the groundwater of the basins in this study,not only in the aspect of application research of groundwater resources of scientific significance,and rational utilization of groundwater resource in valley and basin has practical and guiding significance to the construction of ecological restoration. In this paper,through the use of Shiyang River Basin,Wuwei basin,Minqin Basin,Changning basin such as groundwater depth long-term observation data？ and survey data of underground water level survey regularly,analyze the spatial and temporal variations of groundwater depth,the results show that the basin groundwater buried depth of a downward trend since 1980,buried deep down in the 1990 s,the largest underground water level began to rebound after 2000,the annual variation of groundwater depth is obviously seasonal. The deep space between 1987 and 2006 was strongly changed. To grasp the spatial and temporal changes of groundwater in the research area,it can provide important data support for the establishment of the eco-water scheduling scheme.
