贵州省岩溶地区地下水系统类型及特征分析

Analysis on Types and Characteristics of Groundwater System in Karst Areas of Guizhou Province

我国西南地区地貌类型复杂,既有岩溶地貌,又有侵蚀山脊沟谷地貌。不同地貌类型镶嵌交错,地貌组合复杂多样。含水岩组交错分布,有变质砂岩、页岩、灰岩、白云岩和黏土岩。碳酸盐岩分布广泛,岩溶发育程度对地下水赋存具有控制作用,地质构造对地下水排泄具有绝对的控制作用。本文以贵州省岩溶地区为例,分析研究区地下水系统类型及特征,以查明区内水文地质条件,科学开发岩溶地下水。

Southwest China has complex landform types,including karst landforms and eroded ridge and valley landforms.Different types of landforms are mosaic and interlaced,and the combination of landforms is complex and diverse.The water-bearing rock groups are staggered,including metamorphic sandstone,shale,limestone,dolomite and claystone.Carbonate rocks are widely distributed,the degree of karst development has a controlling effect on the occurrence of groundwater,and the geological structure has an absolute controlling effect on groundwater discharge.This paper takes the karst area of Guizhou Province as an example to analyze the types and characteristics of the groundwater system in the study area,in order to find out the hydrogeological conditions in the area and scientifically develop the karst groundwater.
