四川邻水华蓥山大峡谷地质公园地质遗迹资源体系及地学意义

华蓥山大峡谷地质公园是以峡谷、构造和岩溶地貌为代表的风景地貌类地质公园。本文以华蓥山大峡谷地质公园地质遗迹景观资源为基础, 以川东褶皱带构造单元、川东平行岭谷地貌单元和上扬子地层分区的部分地层区域为研究视角, 构建华蓥山大峡谷地质公园地质遗迹资源体系——包括地质(体、层)剖面、古生物活动遗迹、地貌景观、水体景观以及环境地质遗迹5个大类、15个类共100多处地质遗迹景点; 通过对各类地质遗迹的特征进行分析, 对前人研究进行总结, 探讨了地质公园地质遗迹重要的地学意义。研究表明, 华蓥山大峡谷地质遗迹在地质构造、地层、岩溶学、水文地质学以及地貌学等领域具有重要的科学价值。

The Geological Heritage Resources System of Huayingshan Grand Canyon Geo-park in Sichuan and Its Geographic Significance

The Huayingshan Grand Canyon Geo-park is a kind of scenic landform geo-park with canyon landform, geological structure and karst landform. With the geological heritages in this geo-park as the foundation and the fold belt of Eastern Sichuan basin and paralleled ridge-valley of Eastern Sichuan basin and Wanxian stratigraphic plot as the research visual angle, the authors constructed a complete geological heritage resources system of Sichuan Huayingshan grand canyon geo-park system consisting of 5 categories: geological profiles, biogliph, landform landscape, water landscape and environmental geological heritages, with totally more than 100 geological heritage scenic spots. Based on an analysis of the geological heritage system and the achievements in scientific research, this paper discussed the geographic significance of the geological heritages in Huayingshan Grand Canyon Geo-park. The research indicates that the geological heritages in Huayingshan Grand Canyon Geo-park has important geographic significance for many research fields such as geological structure, strata, karstology, hydrogeology and geomorphology.
