摘　　要：二叠系茅口组古岩溶发育,在一定的构造组合下构成埋藏型地下水系统。本文探讨了贵州省茅口期古岩溶地貌类型及空间分布、不同类型古地貌区的岩溶发育特征,进而对茅口组埋藏型地下水系统和地下水赋存条件进行了探讨。研究结果认为,贵州省茅口期古岩溶地貌可分为台地、斜坡和盆地三大类型,其中古斜坡和台地中的岩溶谷地以及硅质岩分布区茅口组古岩溶最为发育,成为省内茅口组埋藏型地下水系统中最有利的赋存地带。Paleokarst developed in Maokou formation of Permian, formed buried groundwater system in some structural association. In this paper, it discussed the landform type, spatial distribution of paleokarst of Maokou period in Guizhou and karst developed characteristic of different type paleogeomorphology, then the buried groundwater system and groundwater occurrence condition are discussed. According to the study, it＇ s thought that paleokarst landform of Maokou formation can be divided into platform, slope and basin. In addition, karst valley and siliceous rock distribution area of paleoslope and platform are the most developed, becomes the best occurrence area of buried groundwater system of Maokou formation in Guizhou.
