基于地质建造和流域地貌的河北省承德蟠龙湖地区大比例尺地质遗迹调查

Large-scale survey of geological heritage in the Panlong Lake area of Chengde,Hebei Province:Based on geological formations and watershed landforms

基于地质建造分区和流域地貌演化理论,利用地质建造分析、DEM数字地貌、遥感解译、无人机和野外路线调查等技术方法组合,快速查明了承德蟠龙湖景区地质遗迹单体63处,丰富了景区的地质旅游资源,提升了景区的科学内涵。地质建造决定基础地质大类地质遗迹的内在"基因",是地貌景观大类地质遗迹形成的物质基础,并通过岩性和构造影响地质灾害大类地质遗迹的发育。流域地貌演化影响基础地质大类地质遗迹的出露情况;是塑造地貌景观大类地质遗迹形成的主要地质营力,影响地质灾害大类地质遗迹发育。将地质建造和流域地貌相结合的思路贯穿整个地质遗迹调查全过程,初步形成"圈定潜力区—摸清家底—探究规律—总结方法"的大比例尺地质遗迹调查技术方法流程。大比例尺地质遗迹调查的目标是力求打通地质遗迹调查与地方需求、旅游产业发展的"最后一公里",为地质遗迹保护与开发利用、美丽乡村与特色小镇建设提供科技支撑。

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.
