区内新构造运动间歇性抬升迹象明显,侵蚀、溶蚀使石灰岩分布区形成镶嵌在各个不同高程台面上的凹洼地形或条带,深切沟谷的陡壁上往往高悬多层洞穴。在调查区域地貌和地下河系发育演化的基础上分析多层地貌,讨论喀斯特发育史,并探索用统计方法来处理地貌相对年代与生物地层年代的途径。
The signs of intermittent uplift of the Neotectonic movement in the area are obvious. Erosion and erosion cause the limestone distribution area to form the depression or topography or band embedded in the various elevation platforms. The multi-layer caves often hang on the steep walls of the deep gorges. Based on the investigation of the development of regional topography and underground river system, multi-layer topography is analyzed to discuss the history of karst development and to explore ways of using statistical methods to deal with the relative age of geomorphology and the age of biostratigraphy.
