念青唐古拉山地质遗迹特征及世界地质公园创建可行性分析

西藏念青唐古拉山东段地处西藏腹地的拉萨市西北部当雄县，发育了丰富、典型、类型多样的地质遗迹资源.在野外系统调查的基础上，将念青唐古拉山地质遗迹资源划分为纳木错、羊八井地热田和念青唐古拉山冰川地貌为代表的3大类7类11亚类.它们沿该区特有的盆-山构造体系聚集展布，具有极高的科学价值、美学价值和开发利用价值，在全球范围具有典型性、稀有性、完整性和国际对比意义.这些丰富的地质遗迹与佛教建筑融合的文化遗产、高原腹地的生态系统相生相成，全面展示了青藏高原人与自然和谐共生的体系.基于此，从自然文化、范围边界、管理机构、可持续发展经济政策和利益相关者需求等方面分析认为，念青唐古拉山世界地质公园创建优势显著、切实可行、意义重大，进一步提出采用“以地热田为主题的念青唐古拉山世界地质公园”建园方案，采取政府支持、借鉴经验、普及理念、科研保护、旅游产业和社区发展等多维对策，对利用区域绿色地质遗迹资源，促进地方生态文明建设与经济可持续发展具有理论与实践双重意义.

GEOHERITAGE CHARACTERISTICS OF NYENCHENTHANGLHA MOUNTAINS AND FEASIBILITY ANALYSIS ON THE ESTABLISHMENT OF UNESCO GLOBAL GEOPARK

The eastern section of Nyenchenthanglha Mountains, located in Dangxiong County of northwestern Lhasa City, the hinterland of Tibet, is rich in typical and diverse geoheritage resources represented by Namtso Lake, Yambajan geothermal field and glacier landform of Nyenchenthanglha Mountains. The geoheritages can be divided into 3 categories, 7 class and 11 subclasses based on systematic field survey. Clustered and distributed along the basin-mountain tectonic system in the area, the geoheritages are of high scientific, aesthetic and development values, with typicality, rarity, integrity and international comparison significance globally. These rich geological relics complement each other with the cultural heritage of Buddhist architecture and ecosystem in the hinterland of Qinghai-Tibet Plateau, comprehensively demonstrating the most mysterious system of harmony between man and nature on the plateau. It is concluded that the establishment of Nyenchenthanglha Global Geopark is feasible and of great significance with obvious advantages in terms of natural culture, scope boundary, management organization, sustainable economic policy and stakeholder needs. The construction plan of geothermal field-themed Nyenchenthanglha Global Geopark is further proposed with multidimensional countermeasures such as government support, others' experiences, concept popularization, scientific research protection, tourism and community development, which provides theoretical and practical basis for utilization of regional green geoheritages and promotion of local eco-civilization construction and economic sustainable development.
