一、岩溶地下水的补给岩溶地下水的总补给源为大气降水。从产流的角度观察,它的补给方式可分为直接补给与间接补给。若分析水流运动的性质,又可分为渗入补给和钻入补给。直接补给为大气降雨直接通过灰岩表面的裂隙、溶沟、断层以及其它通道下降钻入灰岩岩层,形成岩溶地下水。间接补给为大气降雨补给覆盖在灰岩地层上部的第四系潜水,然后由潜水转化为深层岩溶地下水。本文主要探讨大气降雨对上部裸露灰岩的直接补给问题。从地貌、地质构造及水文条件的分析
First, the supply of karst groundwater karst groundwater recharge the total supply of atmospheric precipitation. From the perspective of runoff, it can be divided into direct supply and indirect supply. If you analyze the nature of water movement, but also into the infiltration of supply and drilling supplies. Direct recharge to the atmosphere directly through the limestone fissures, ditches, faults and other channels down into the limestone rock formation karst groundwater. Indirect recharge recharges Quaternary supplies covering the upper part of the Limestone Formation for atmospheric rainfall and is then converted from deepwater to deep karst groundwater. This paper mainly discusses the direct recharge of upper bare limestone by atmospheric rainfall. From the topography, geological structure and hydrological conditions analysis
