摘要
甘肃临潭冶力关国家地质公园为研究对象,按照规范将其地质遗迹划分为3大类7类13亚类。通过与国内其他地质公园对比分析,公园内具有系统完整的以赤壁幽谷为代表的丹霞地貌,紧邻河流以及半湿润的气候条件使其具有南方丹霞地貌特有的"顶平、身陡、麓缓"特征,成为西北地区的高寒湿润型丹霞地貌的典型代表。冶海古滑坡体遗存特征明显,保存完整,整个滑坡过程甚至滑坡后产生的地质遗迹也非常丰富,系统性较高。形成的堰塞湖规模巨大,使得冶海成为典型的高山堰塞湖。冶木峡东峡景区及冶海景区由二叠系与石炭系地层形成岩溶地貌,岩溶作用与新构造运动、流水作用共同塑造了不同景区各具特色的岩溶景观。发育有深峡幽谷、岩溶泉、十里卧佛、溶蚀洼地等特色岩溶地貌,景观典型独特,保持自然状态,系统完整,极大地丰富了公园的地质地貌类型。这些地质遗迹组合,使公园具有很高的科普教育价值、美学观赏价值和旅游开发价值。
Geoheritages are the core of geopark construction. This paper divides geoheritages of the Yeliguan National Geopark in Lintan, Gansu into 3 categories, 7 types and 13 sub-types. The comparison with other geoparks in China indicates that the Yeliguan National Geopark has a complete system of Danxia landform represented by the Red Wall Valley. Thanks to adjacency to the river and the semi-humid climatic conditions, the Danxia landform here is typical representative of alpine moist Danxia landform in northwest China and is characterized by "top level, steep body, slow foothills" of Danxia landform in south China. It is a typical representative of the alpine and humid Danxia landform in the northwestern region. The remains of the Yehai ancient landslide body are obvious and perfectly preserved. The geoheritages produced during the entire landslide process and even after the landslide are also very rich and systematic. The Yehai Lake is a huge and typical alpine landslide barrier lake. The karst landforms in the east Yemuxia gorge and Yehai spots were formed from the Permian and Carboniferous strata. Unique karst landscapes such as deep gorge, karst spring, Shili Decubitus Buddha and corroded depression resulting from karstification, neotectonism and runoff erosion greatly enriches the geological and geomorphological types of the park. These geoheritage combinations make the park a high values of popular science education, aesthetic appreciation and tourism development.
