摘要:

建立国家地质公园是保护地质遗迹、促进黄河流域生态保护与高质量发展的有效途径之一,而地质遗迹的调查与评价又是地质公园规划与建设的重要基础。青海省化隆县地处青藏高原东北缘,黄河流经该县168 km,具有丰富的黄河文化遗存,但地质遗迹资源能否达到建设地质公园的要求尚不清楚。本文在地质遗迹调查的基础上,采用专家打分及层次分析法,对化隆县地质遗迹的价值进行定量评价,初步确定了拟建的化隆国家地质公园的边界范围。园区内地质遗迹共计40处,涵盖6大类,9类20亚类,其中包括2处世界级地质遗迹组合、6处国家级地质遗迹。拉脊山早寒武世缝合带、西宁群—化隆岩群角度不整合等地质遗迹,具有原特提斯洋演化、青藏高原隆升等重要的科学价值及国际对比意义。化隆县地质遗迹种类丰富、特征明显、价值极高且保存完好,具备良好的建设国家地质公园的资源禀赋,拥有申报联合国教科文组织世界地质公园的潜力。本研究不仅为化隆国家地质公园的申报及建设提供了科学依据,也为黄河流域具有国际影响力的文化旅游带的打造提供了参考。

Abstract:

Establishing national geopark is an effective way to protect geoheritage as well as promote ecological protection and high-quality development of the Yellow River Basin. Also, investigation and assessment of geoheritage are significant to the design and construction of geopark. Hualong county is located at the northeastern margin of Qinghai-Tibetan Plateau, and has rich Yellow River cultural relics since the river flows through the county for 168 km. But systematic research is still needed to verify if the geoheritage distributed in the county can meet the requirements of geopark. Based on the geoheritage investigation, this paper quantitatively assesses the value of geoheritage distributed in Hualong county by analytic hierarchy process (AHP),and the boundary of the proposed Hualong National Geopark is confirmed. 40 geoheritages are found in the geopark, covering 6 large categories, 9 categories and 20 sub-categories, including 2 world-class, 6 national-class geoheritages. Among them, Early Paleozoic suture zone on Mount Lajishan, as well as angular unconformity between the Xining Group and Hualong Complex, have significant scientific and global correlation value on the evolution of the Proto-Tethyan Ocean and the uplift of the Qinghai-Tibetan Plateau, separately. The result shows that Hualong county is well of various, characteristic, significant-value and well-preserved geoheritages, which have the resource natural endowment for establishing National Geopark and the potential to be listed as a UNESCO Global Geopark. This paper provides not only scientific evidence for the application and construction of Hualong National Geopark, but also references for creating the Yellow River Cultural Tourism Belt.
