洛塔表层岩溶带水文地质特征及其水文地质结构类型

在简述洛塔地区自然地理、岩溶及水文地质基本特征的基础上,对区内表层岩溶带的水文地质特征及表层岩溶带水文地质结构进行了较详细的分析和论述。提出了查明表层岩溶带水文地质结构是研究表层岩溶带水文地质子系统调蓄能力的关键所在的观点。根据表层岩溶带的水动力条件类型、含水空间结构类型、碳酸盐岩类型及第四系土层覆盖情况,将区内表层岩溶带水文地质结构划分为12个具体类型。并对各表层岩溶带水文地质结构类型的主要水文地质特征、调蓄能力及其地下水的开发利用条件等进行了简要的评述。 

HYDROGEOLOGIC STRUCTURE AND FEATURE OF THE EPI-KARST IN LUOTA

On the basis of briefly introducing the physical geography, karst and hydrogeologic basic features, the hydrogeologic structure and hydrogeologic features of the epi-karst water are analyzed in detail in the paper. It is put forth that the key work for the study of the adjusting ability of the epi-karst sub-system is to make clear the hydrogeologic structure of the epi-karst. Twelve types of hydrogeologic structure in epi-karst zone are divided accounting for the water hydraulic condition, spatial structure type of the aquifer, lithology of the carbonate rock and the overlying sediment of the Quaternary Period. The major hydrogeologic features, the adjusting ability and the condition for groundwater development and exploitation in each hydrogeologic structure type of the epi-karst zone are briefly evaluated.
