摘　　要：在气候变化的大背景下,近数十年来随着北方岩溶区降水量的趋势性下降和气温的不断升高,岩溶水补给资源量大幅度衰减,气候变化成为引发一系列岩溶水文地质环境问题的原因之一。针对这一问题,以岩溶水系统为单元,采用大量气象系列资料研究北方岩溶区降水变化与分布特征,分析了气候变化发展趋势及成因,从区域角度出发,估算了气候变化对岩溶水资源的影响。In recent decades,with the decreasing precipitation and rising temperature under a background of climate change in the karst areas of northern China,the recharge of groundwater in the karst areas has declined sharply.The climate change has been one of the causes that lead to a series of environmental problems of karst hydrogeology.This article deals with this problems in 3 aspects：（1） taking groundwater systems in karst areas as a unit of measurement,the change and distribution of precipitation in karst areas in northern China are examined;（2） the climate change and its causes are analyzed with statistic methods;（3） the effects of climate changes on groundwater resources in karst area on a regional scale are estimated.
