黔西北地区岩溶水系统划分及找水方向

黔西北地区水文地质条件复杂,岩溶水系统小型多样,传统的岩划分方法难以较准确地刻画溶水系统特征,本文根据区内地质构造、地形地貌以及地表水文网对地下水补、径、排条件的控制,提出一种将岩溶水系统划分成封闭型和开放型系统的新方法。以新的划分方法为基础,重点阐述了开放型岩溶水系统中有利地下水富集、适宜成井的微观条件,指出了不同岩溶水系统地下水开发利用方向。

Division of Karst Water System and Water Prospecting Direction in Northwest Guizhou

In the northwest Guizhou, the hydrogeological condition is complex, the karst water system is small and multiplex, the traditional method is hard to find the system character. According to the regional geological structure, landform and the control of groundwater recharge, runoff and drainby the surface hydrological net, a anew method which divide the karst water system into close and open system is carried out. The new method as the basis, it narrates the microscopic condition that the open water system is good for groundwater concentration and easy to form well. The prospecting and usage direction of different karst groundwater system is carried out.
