Huainan is located at the boundary between north and south of China. Due to its unique geotectonic location and long geological evolution history, Huainan has formed a special karst landform. The karst landscape and karst development process of the Cambrian Ordovician in this area are analyzed from the aspects of stratigraphic distribution, crustal movement evolution and groundwater recharge conditions. It is concluded that large karst caves are developed in the karst multi-shun layer in the study area, in carbonate rocks. The surface development of the joint fissures is mostly filled with calcite, the erosive gully is developed in the concentrated area of the flowing water, and the karst landscape such as the beaded karst is developed near the fault zone.
