褒禅山华阳洞的形成机理及保护意义

摘要

The Huayang Cave of the Baochan Mt. is developed in the Permian Qixia Formation of limestone as one of important geological relics in the Hanshan area. From regional geological evolution, the material basis of karst caves, local structural conditions, water flow directional erosion, and neotectonic movement, this paper briefly analyzed the formation mechanism of the Huayang Cave, and pointed out its protection value in view of geoscientific research and tourism economy.%褒禅山华阳洞主体发育于二叠系栖霞组灰岩中，是含山地区重要的地质遗迹之一。笔者从区域地质演化过程入手，针对岩溶洞穴发育的物质基础、局部构造条件、水流的定向溶蚀及新构造运动等方面进行综合研究，简要分析了华阳洞的形成机理，并从地学研究、旅游价值等方面阐述了对其保护的重要意义。
