长江三峡国家公园建设地质条件分析与价值评估研究

Geological condition analysis and value evaluation research of Three Gorges National Park of Yangtze River

为了研究论证长江三峡地区地质条件与价值,为建设长江三峡国家公园确定核心资源价值奠定基础,通过全面分析长江三峡地区区域地质遗迹的类型、数量、分布和规模,对区域地质遗迹的价值指标体系进行评估,最终确定其地质遗迹价值等级。结果表明:长江三峡地区共有重要地质遗迹149处,以岩溶地貌、峡谷和层型(剖面)地质资源为主,总占比66%。地质遗迹价值具有世界级价值的有13处,具有国家级价值的有64处,具有省级价值的有75处。长江三峡国家公园地质遗迹资源的核心价值定位为层型(典型剖面)、岩溶地貌和峡谷地貌资源库。研究结果能够为长江三峡国家公园建设提炼具有重要价值的地质类核心资源提供参考。

In order to analysis the geological conditions and the value of the Three Gorges area of the Yangtze River,to lay a foundation for the construction of the Three Gorges National Park and determine the core resource value.Through the comprehensive analysis of the type,quantity,distribution and scale of the regional geological relics,and evaluate the value index system of regional geological relics,finally determined the value grade of the geological relics.The result shows that,there are 149 important geological relics in the Three Gorges area of the Yangtze River,which are mainly karst landform,gorge and stratotype section geological resources,accounting for 66%of the total.There are 13 geological relics with world-class value,64 with national-class value and 75 with provinciallevel value.The core value orientation of geological heritage resources in the Three Gorges National Park is stratotype(typical section),karst landform and gorge landform resource pool.The research results can provide reference for the construction of the Three Gorges National Park of Yangtze River to extract the geological core resources with important value.
