Based on the geological formation zoning and watershed landform evolution theory and using a combination of technical methods such as geological construction analysis, DEM digital landforms, remote sensing interpretation, unmanned aerial vehicle and field route survey, the authors quickly identified 63 single geological heritages in Chengde Panlong Lake, and this enriches the geo-tourism resources of the scenic area and enhances the scientific connotation of the scenic area. Geological formation determines the inherent "gene" of the basic geological heritage, is the material basis for the formation of geological heritage of geomorphic landscapes, and affects the development of geological heritage of geological disasters through lithology and structure. The evolution of watershed geomorphology affects the exposure of basic geological heritage; it is the main geological force that shapes the formation of geological heritage of geomorphic landscapes and affects the development of geological heritage of geological disasters. The idea of combining geological formation and watershed geomorphology runs through the whole process of geological heritage survey, and a large-scale geological heritage survey technical method flow of "defining the potential areaidentifying geological heritage resources-inquiring laws-summary method" is initially formed. Large-scale geological heritage surveys strive to bridge the"last mile"of geological heritage surveys and local needs as well as the development of the tourism industry, and provide scientific and technological support for the protection and development of geological heritages and the construction of beautiful villages and characteristic towns.
