AccordingtoMaokorformationofpaleogeomorphologyandoverlyinglayerdistributioncharacter-istics,this research collects data of field investigation,the actual exploration data compilation,the characteris-tics of palerkarst development and water content on the research section were compared.The results show that, in the basult and siliceous rocks covered area in the west,karst is developed intensely,and the water-abun-dance is better.And Longtan formation clastic rock and Wujiaping limestone coverage in the east,karst devel-opment is weak and poor water.The characters of paleo landform and the influence of different upper layer li-thology to the spatial distribution and water yield property,the hydro-geological significance of paleo kars zpne of Maokou formation in the target area.%本文根据茅口组古地貌及上覆地层岩性分布特征，以野外调查和实际勘探试验资料为依据，采用典型剖面对比分析的方法，对贵州省二叠系茅口组古岩溶带发育及富水性特征进行了研究。研究结果表明，在西部玄武岩及省内局部硅质岩覆盖区，茅口组古岩溶发育最为强烈、富水性良好，而东部龙潭组碎屑岩、吴家坪组灰岩覆盖区，深埋藏条件下的茅口组古岩溶整体发育及富水性程度相对减弱。进而讨论了古地貌特征及不同上覆地层岩性对古岩溶带空间分布及富水性的影响、初步探讨了研究区茅口组古岩溶带的水文地质意义。
