岩溶山区多年的地下水开发利用实践证明,传统的岩溶地下水系统划分不利于指导岩溶山区勘查找水和地下水资源的开发。为了更好地指导岩溶山区地下水资源的勘查和开发,文章从有利指导岩溶山区地下水勘查和开发利用的角度,在继承传统划分方法的基础上,提出了一种新的以地下水的赋存条件、富集条件,以及开发条件三个层次组合的地下水系统综合划分方法:根据岩溶地下水系统与供水目标在空间上的关系划分为“高位”和“低位”两种类型,根据控制地下水富集的水文地质结构划分为“开放”和“封闭”两个亚类,根据地下水的水动力和排泄特点划分为集中(地下河、岩溶泉)和分散排泄三类系统,并给出了“高位”型地下水系统开发成本低、“封闭型”地下水系统资源丰富,“封闭型地下水系统”是缺水区勘查找水的主要目标,合理的岩溶水系统的开发利用应按照“高位封闭型”、“高位开放型”、“低位封闭型”的顺序进行规划部署,“低位开放型”地下水系统则因富水性差、开发利用成本高可作为储备水源地的建议。
巖溶山區多年的地下水開髮利用實踐證明,傳統的巖溶地下水繫統劃分不利于指導巖溶山區勘查找水和地下水資源的開髮。為瞭更好地指導巖溶山區地下水資源的勘查和開髮,文章從有利指導巖溶山區地下水勘查和開髮利用的角度,在繼承傳統劃分方法的基礎上,提齣瞭一種新的以地下水的賦存條件、富集條件,以及開髮條件三箇層次組閤的地下水繫統綜閤劃分方法:根據巖溶地下水繫統與供水目標在空間上的關繫劃分為“高位”和“低位”兩種類型,根據控製地下水富集的水文地質結構劃分為“開放”和“封閉”兩箇亞類,根據地下水的水動力和排洩特點劃分為集中(地下河、巖溶泉)和分散排洩三類繫統,併給齣瞭“高位”型地下水繫統開髮成本低、“封閉型”地下水繫統資源豐富,“封閉型地下水繫統”是缺水區勘查找水的主要目標,閤理的巖溶水繫統的開髮利用應按照“高位封閉型”、“高位開放型”、“低位封閉型”的順序進行規劃部署,“低位開放型”地下水繫統則因富水性差、開髮利用成本高可作為儲備水源地的建議。

It has been proved that traditional division schemes of karst groundwater system are not favorable to water exploration and utilization.In order to guide the karst area groundwater exploration and develop-ment better,a new classification scheme is proposed based on conditions of occurrence,enrichment and ex-ploitation.According to the spatial relationship between the karst groundwater systems and supply targets, they are classified into "high"and"low" types.Upon the key hydrogeological structure,they are divided as"open" and"closed" subclasses.In light of groundwater hydrodynamic characteristics and drainages,they are compartmentalized into “focus”(underground rivers,karst springs)and"divergent drainage"systems.In addition,it is pointed out that exploration of "high" groundwater systems is of low cost,"closed" systems have abundant groundwater resources which are the main targets of exploitation.Rational development and utilization of karst water systems would be in accordance with the order of"high-closed","high-open",and" low-closed" .Due to poor enrichment of groundwater and high cost," low-open" systems can be used as reserve water sources.
