摘要
贵州是以碳酸盐岩地层分布为主的省份,岩溶十分发育,大气降水是地下水的主要补给源。自2000年以来,贵州旱涝灾害频繁,受灾面积大,特别是2010年百年一遇大旱,灾情严重。本文根据近50年来的监测资料,采用回归分析方法,分析了降水量和岩溶地下水资源量之间的变化特征,为贵州合理开发利用地下水资源提供依据。
in geology,Guizou was mainly composed of carbonate rock layers,where karst was well developed and the groundwater was replenished by atmospheric precipitation. Since the year 2000,droughts and floods happened frequently and a large number of areas in Guizhou were affected,especially in 2010 it occurred the worst flood in a century. In this paper,we collected the rainfall and groundwater information of recent 50 years,and made the regression analysis,in order to reveal the relationship between precipitation and karst groundwater resources.
