摘要
简要介绍了河西走廊石羊河、黑河、疏勒河三大流域内近5 0年来地表水出山迳流量、流域平原区地下水资源补给量、泉水溢出量、地下水开采量的历史变化,对不同时期地下水均衡结果进行了比较,初步分析了地下水资源减少的原因。
The historical changes in surface water runoff amount from mountain areas in recent 50 years, the recharge quantity of groundwater resources in drainage plain regions and the exploitation of groundwater in the three drainage area of the Shiyanghe river, Heihe river, and Shulehe river in the Hexi corridor are briefly introduced in the paper. The results of groundwater balance in different periods of time are compared, and the causes of decrease in groundwater resources are also analyzed.
