隐伏岩溶区的水文地质分带和定量评价(二)——以山西延河泉域为例

HYDROGEOLOGIC ZONALITY AND IT'S QUANTITATIVE EVALUATION IN LIE CONCEALED KARST REGION

7.泉域隐伏区主要含水层(组)的水平分带在用统计法获得隐伏岩溶区主要层(组)“垂向”分带标高和相应指标的基础上,便可作研究区的水平分带图,即把不同迳流带的分带标高,分别放在“奥灰”顶面等值线图上,便获得泉域隐伏岩溶分布区的水平分带图(图5),图中由边部到中部划分为强迳流带、中等迳流带、弱迳流带,实线和数字为分带界线和标高,虚线和数字为富水性界线和标高。

Based an the correlation analysis between genera lhydrogeologic, pumping test and hydrochemical data and O_2 limestone aquifer (?)roof elevation,a series, of curves and equations are obtained, which are used to make hydrogeological zonation in space, to give relevant evaluation indices, to divide runoff zones,and to define the boundry condition and the optimum water supply area for prospecting and drilling in the research. region. Furthermore, with the theory of chemical thermodynamics and kinetics,the permeability and zoning of O_2 aquifer are defined, and a solid foundation for the evaluation and management of water resources is thus established. Practice has proved that the theory and method shown above are reliable.
