贵州碧江石林地质公园地质遗迹特征及其地学意义

Geological Relics Characteristics and Its Geological Significance in Bijiang Stone Forest Geopark,Guizhou

贵州碧江石林地质公园是以石林喀斯特为主,溶洞、侵蚀峡谷、泉水溪流为辅,集地质剖面、地质构造、古油茶树等景观资源为一体的省级小型地质公园。公园处在贵州高原向湘西丘陵过渡的斜坡地带,地质遗迹资源较典型,且具观赏和美学价值,主要分为地质剖面、地质构造、地貌景观、水体景观4个大类,6个类,共30余处地质遗迹景点。在山顶斜坡相对封闭的独立喀斯特单元中,有限可溶地层发育了规模较大的石林喀斯特,代表了贵州高原晚新生代喀斯特地貌发育演化的典型范例,具有区域对比意义,在地质学、地貌学及地学旅游等领域具有重要的研究价值。研究结果对于系统认识公园地质遗迹状况、地质遗迹保护和开发、建立地学科普研学基地等具有一定参考和借鉴意义。

Bijiang Stone Forest Geopark is a small provincial geopark based on karst forest,supplemented by karst caves,erosion canyons and spring streams.It integrates landscape resources such as geological section,geological structure and ancient oil tea trees.The park is located in the slope area of transition from Guizhou Plateau to Xiangxi Hills,with typical geological heritage resources and ornamental and aesthetic value.It is mainly divided into 4 categories of geological section,geological structure,geomorphic landscape and water landscape,and 6 categories,with a total of more than 30 geological heritage sites.In the relatively closed independent karst unit on the mountaintop slope,a large scale stone forest karst has developed in the limited soluble strata,which represents a typical example of the development and evolution of late Cenozoic karst in the Guizhou Plateau,and has regional comparative significance,and has important research value in the fields of geology,geomorphology and geoscience tourism.The research results have certain reference significance for the systematic understanding of the geological heritage status of the park,the protection and development of geological heritage,and the establishment of science popularization research base.
