西南地区岩溶水源地类型及开发技术条件

Classification and exploitive technical condition of karst water source field in southwest China

明确了岩溶水源地的定义,并提出了新的岩溶水源地分类方案。首先按岩溶含水层的埋藏分布、岩溶水出露状态,将岩溶水源地划分为天然出露的岩溶水源地及隐伏的岩溶水源地两大类。然后再根据岩溶水源地的岩溶含水介质特征(导水和赋水空间形态、结构及水动力特征)进一步将天然出露的岩溶水源地划分为暗河、泉、表层泉三个亚类,将隐伏的岩溶水源地划分为饱水带富水块段、表层带富水块段两个亚类。并研究评价了各个类型的岩溶水富集规律、动态特征、岩溶水资源、开发技术条件。

It is redefined the meaning of ＂karst water source field＂ and put forward a new category of ＂karst water source field＂ in this paper.Firstly,based on the situation of aquifer distribution and outcrop state of karst water,the new category classifies the karst water source field into two broad types： ＂natural outcropped karst water source field＂ and ＂buried karst water source field＂.Secondly,based on water-bearing medium,water conduit and storage place and structure,water dynamic feature,the ＂natural outcropped karst water source field＂ is subdivided into three subtypes： ＂underground river＂,＂karst spring＂ and ＂epikarst spring＂.The ＂buried karst water source field＂ is subdivided into ＂saturation zone water-rich block＂ and ＂epikarst zone water-rich block ＂.In addition,the law of water enrichment,the regime and exploitive technical conditions of the karst water are also studied in the paper.
