构建合理的地质公园资源承载力评价指标体系,是进行地质公园资源承载力评价的关键。创新性地运用广义地球系统理论明确地质公园资源承载力的内涵,利用美国国家公园管理(NPS)使用的游客体验与资源保护VERP法筛选地质公园资源承载力评价指标,不仅从宏观层面搭建地质公园资源承载力综合评价指标体系,还从微观层面为指标筛选提供可行的原则,最终建立分层次的地质公园资源承载力综合评价指标体系:一级指标有地球亚系统资源承载力、自然环境亚系统资源承载力和社会环境亚系统资源承载力;二级指标有水圈资源承载力、岩石圈资源承载力、大气圈资源承载力、生物圈资源承载力等12个指标;三级指标有水体面积、水资源可利用量、年均降雨量、大气含氧量、地质遗迹的稀有性和典型性等31个指标。地质公园资源承载力综合评价指标体系的建立,对于保护地质遗迹、保护生态环境、可持续开发利用资源具有重要意义。
Constructing a reasonable evaluation index system of resources carrying capacity of geoparks is the key to evaluate the carrying capacity of resources of geoparks. Using the theory of generalized earth system to clarify the connotation of the resource carrying capacity of geoparks, using the VERP method of tourist experiences and resources conservation in the National Parks Management (NPS) to select the evaluation index of the resource carrying capacity of the geopark, we not only construct the geopark Resource comprehensive evaluation index system of carrying capacity, but also provide viable principles for index screening from the micro-level, and ultimately establish a comprehensive evaluation index system of geological resources carrying capacity at different levels: the first level indicators of the Earth’s sub-system resources carrying capacity, sub-system of natural environment Resource carrying capacity and social system sub-system resource carrying capacity. The second level indicators include hydrosphere carrying capacity, carrying capacity of lithosphere resources, carrying capacity of atmospheric resources and carrying capacity of biosphere resources. Third-level indicators include water area, Water resources availability, average annual rainfall, atmospheric oxygen content, the rareness and typical of geological relics and other 31 indicators. The establishment of comprehensive evaluation index system of resource carrying capacity of geoparks is of great significance for the protection of geological relics, the protection of ecological environment and the sustainable development and utilization of resources.
