深切河谷斜坡地带岩溶地下水的赋存特征及开发利用——以石阡县安家寨地下水系统为例

Occurrence Characteristics and Utilization of Karst Groundwater in Slope Zone of Deep Valley——Taking the Groundwater System of Anjiazhai in Shiqian as an Example

本文以石阡县安家寨片区开放型岩溶地下水系统为研究对象,以石阡县安家寨地区的实际勘查成果为基础,指出了在该类型地区受地质构造控制,可能存在局部封闭型的阻水型蓄水构造,成为该类型地区寻找和开发利用地下水的有利地带。并在此提出在深切河谷斜坡地带寻找有开发价值的地下水源地的方向为:在"开放型"水文地质系统中寻找局部的"封闭型的地下水蓄水构造",可作为该类型地区勘查和开发岩溶地下水的借鉴。

The deep valley traversed with slope zone of fold flank closely, the valley became the drainage base level of groundwater ans caused the deep bury, the spatial distribution was also homogeneous, the surface drought was serious, the karst eco-environment was weak and the difficulty of seeking valuable water source was big. In this paper, the open karst groundwater system in Anjiazhai was taken as example, with the guid-ance of tectonics, hydrogeology and karstology, on the base of actual exploration results in Anjiazhai area, it＇s found this area was controlled by structure, maybe has partial closed water-clocked reservoir structure and be-came the advanced zone for groundwater exploration in this kind of area. It also carried out that the direction of valuable groundwater source seeking in slope area of deep valley seek closed water - clocked reservoir structure in open hydro-geological system, it can be the example of karst groundwater exploration and utiliza-tion in this kind of area.
