柴埠溪大峡谷形成演化及造景地质作用

Formation evolution and landscaping geological process of Chaibuxi Grand Canyon

柴埠溪大峡谷属典型的岩溶峡谷,汇集了早期、中期、晚期3个层次的岩溶地貌,是开展地貌演化和造景地质作用研究的理想场所,其独特的岩溶景观给地貌演化、水文演化及造景地质作用赋予了新的内涵。地层岩性、地质构造、地貌演化为柴埠溪大峡谷的形成提供了独特的地质背景,新构造运动、表生改造、气候变迁、水文演化共同作用,塑造了具有“雄、奇、险、秀、幽”特征的柴埠溪大峡谷景观。在地史分析的基础上,采用地质过程分析方法,推演了柴埠溪大峡谷地貌的形成过程,总结了区域造景地质作用,对柴埠溪地质公园建设研究及科学旅游具有重要的理论与现实意义。

Chaibuxi Grand Canyon is a typical karst canyon,which gathers three levels of karst landforms in the early,middle and late periods.This kind of canyon is an ideal place for the study of geomorphic evolution and landscape geological processes.Because of its unique karst landscape,it has achieved new connotation of geomorphic evolution,hydrologic evolution and geological process of landscape construction.The formation lithology,geological structure and geomorphologic evolution provide a unique geological background for the formation of Chaibuxi Grand Canyon.The combination of neotectonic movement,epigenetic transformation,climate change and hydrological evolution shapes the landscape of Chaibuxi Grand Canyon effectively,with the typical characteristics of“magnificent,strange,dangerous,beautiful and secluded”which attracts people's attention.On the basis of geological history analysis and geological process analysis,this study work deduces the geomorphic formation process of Chaibuxi Goand Canyon and summarizes the geological function of regional landscape.These valuable research results and new discoveries manifests important theoretical and practical significance for the research and construction of Chaibuxi Geoparks and scientific tourism.
