本文论述了滇东地区岩溶盆地的水文地质特征,按结构——成因的原则进行了类型的划分,分为(1)底伏压流溶蚀盆地;(2)并迭潜流压流侵蚀溶蚀盆地;(3)多层潜流压流自流断陷盆地。对上述各类盆地建立了水文地质模式,综合了它们的含水层时代、厚度和埋深,水位和流量,地下水类型。提出滇东岩溶盆地有两个发育时期,一是新第三纪形成断陷盆地及部份溶蚀盆地:二是第四纪形成侵蚀盆地及一些溶蚀盆地。
This paper discusses the hydrogeological features of karst basins in eastern Yunnan, and is divided into three types according to the structure-genesis principle: (1) bottom pressure flow erosion basin; (2) (3) multi-layer subsurface flow pressure gravity flow basin. Hydrogeological models have been established for all of these basins, combining their aquifer age, thickness and depth, water level and flow, and groundwater types. It is suggested that there are two developmental stages in the eastern Yunnan karst basin. One is the Neoproterozoic faulting basin and some dissolution basins. The other is the Quaternary sedimentary basin and some erosion basins.
