| 摘 要： | 断陷盆地是云南省主要的盆地类型.研究断陷盆地岩溶水赋存规律,对于科学地寻找和合理地开发利用岩溶水资源,具有重要的社会经济意义.通过总结云南岩溶断陷盆地中岩溶水形成规律,并对典型断陷盆地进行研究,归纳了裸露型、裸露-覆盖型、裸露-埋藏型和滞水型4类浅循环岩溶水的赋存特征.裸露型岩溶区具不均匀的洞隙系统,为快速管道流,覆盖型岩溶区含水层等效于多孔介质特征,其垂向上的分层结构差异较大,多为幔速扩散流,地下水多在盆谷地边缘呈暗河、大泉方式排泄,深覆盖区、埋藏区往往补给不畅,水量有限,应着重于暗河和大泉的调查及其补给迳流区的研究;滞水型属有阻条件的裸露型岩溶水,赋水分散且水量有限,适宜解决山区缺水困难.针对云南不同大地构造区断陷盆地,提出相应的岩溶水合理开发方式.

| Abstract: | Fault basin is the primary type of basins in Yunnan Province.It is socially and economically significant to study the occurrence and reasonably utilized the resource of the karstic water in the fault basins.By strudy on typical fault basins,four occurrence types of shallow circulated karstic water are recognized,i.e.exposed type,exposed covered type,exposed buried type and stagnant type.In the area of exposed type of karst,cavity systems are unevenly distributed with fast pipeline flow.In the covered type area,the water bearing strata are equal to porous media,of which the layered structure varies vertically.Most of them are the slow and spread flow.The groundwater discharges by way of underground river or heavy spring at the edge of basin valley.The stagnant type belongs to exposed karstic water in resisting condition with scattered and limited water,which is suitable to solve the problem of water shortage in mountainous distrcts.For the fault basins in different tectonic areas in Yunnan Province,the karstic water should be developed in corresponding rational ways. |
