甘肃临潭冶力关国家地质公园地质遗迹资源及旅游地学意义

GEOHERITAGE RESOURCES AND TOURISM EARTH SCIENCES SIGNIFICANCE OF THE YELIGUAN NATIONAL GEOPARK IN LINTAN,GANSU PROVINCE

地质公园的建设和发展以地质遗迹为核心。甘肃临潭冶力关国家地质公园主要以丹霞地貌、滑坡堰塞湖和西北岩溶地貌为主,集旅游、休闲、探险和科研于一体的综合性地质公园。公园位于西秦岭造山带西段,属中秦岭断褶带,地质遗迹丰富典型且在西北稀有,可分为3大类7类13亚类。通过定量评价可以看出,地质遗迹具有很高的科学研究价值、美学观赏价值和旅游开发价值。区内出露上古生界和新生界地层,以区域大型褶皱构造为主,冶海古滑坡形成的堰塞湖规模巨大,滑坡遗存特征明显,保存完整,发育的丹霞地貌为典型的西北高寒湿润型丹霞地貌,在构造地质学、地层学、灾害地质学、地貌学以及生态学等各领域具有重要的研究价值。本文的研究结果对于正确认识冶力关国家地质公园地质遗迹状况,深入的进行地质遗迹的保护与开发具有一定的参考和借鉴价值。

The construction and development of the geopark is centered on geoheritage. The Yeliguan National Geopark in Lintan of Gansu province integrates tourism, leisure, exploration and scientific research into a comprehensive Geopark, which mainly focuses on Danxia landform, landslide dammed lake and northwest karst landform. The park is located in the western part of the West Qinling orogenic belt and belongs to the Middle- Qinling fault fold belt. Geoheritage is abundant and rare in the northwest. It can be divided into 3 categories, 7 categories and 13 sub-categories. It can be seen from quantitative evaluation that geoheritage have high scientific value, aesthetic value and tourism development value. The area is exposed to the Upper Paleozoic and Cenozoic strata, with regional large fold structures. The landslide dammed lake formed by the Yehai ancient landslide is huge in scale, and the remains of the landslide are obvious and preserved intact. The developed Danxia landform is a typical northwest alpine and humid type Danxia landform. It has important research value in various fields such as structural geology, stratigraphy, disaster geology, geomorphology and ecology. The research result of this paper has a certain reference significance in such aspects as correct understanding of the condition of geoheritage of the Yeliguan National Geopark, and the in-depth protection and development of geoheritage.
