海南热带雨林国家公园重要地质遗迹特征及综合评价

Characteristics and comprehensive evaluation of important geoheritages in Hainan Tropical Rainforest National Park

海南热带雨林国家公园内地质遗迹资源是热带雨林内自然资源和自然环境极其重要的组成部分,地质遗迹所赋存的地质环境,是热带雨林生物多样性的基础条件。推进地质遗迹资源的科学保护和合理利用是建设海南热带雨林国家公园的重要内容之一。基于对海南热带雨林国家公园全面系统的地质遗迹调查评价工作,依据《地质遗迹调查规范》(DZ/T 0303-2017),笔者等系统的总结了海南热带雨林国家公园内重要地质遗迹资源的特征和分布,对其科学价值和美学价值进行了定性和定量综合分级评价。研究结果表明:海南热带雨林国家公园内地质遗迹类型多样,以基础地质和地貌景观大类为主,包括重要化石产地类、岩土体地貌类、水体地貌类以及火山地貌类4类,古生物群化石产地、岩溶地貌、侵入岩地貌、碎屑岩地貌、瀑布、火山岩地貌6个亚类,共计21处重要地质遗迹点。其中,世界级地质遗迹点的有1处,省级地质遗迹点17处,省级以下地质遗迹点3处。通过对海南热带雨林国家地质公园地质遗迹评价,为国家公园内地质遗迹资源保护和利用提供基础资料和思路。

Objectives:The geoheritage resources in Hainan Tropical Rainforest National Park are extremely important components of the natural resources and natural environment in the tropical rainforest.The geological environment of the geoheritage is fundamental to the biodiversity of the tropical rainforest.The scientific protection and rational utilization of geoheritage resources is one of the important contents of the construction of Hainan Tropical Rainforest National Park.It is important to provide basic information and ideas for the protection and utilization of geoheritage resources in the National Park.Methods:Based on the comprehensive and systematic investigation and evaluation of geoheritage resources in Hainan Tropical Rainforest National Park,according to the‘specification for geoheritage investigation(DZ/T 0303-2017)’,this paper systematically summarizes the characteristics and distribution of important geoheritage resources in Hainan Tropical Rainforest National Park,and conducts a qualitative and quantitative comprehensive evaluation and classification of their scientific and aesthetic values.Results:The research results show that there are various types of geoheritage in Hainan Tropical Rainforest National Park,with the main categories being fundamental geology and geomorphological landscape,including 4 categories:important fossil production area,important fossil origin category,rock and soil geomorphology,water geomorphology and volcanic geomorphology,and 6 subclasses:Paleobiota Fossil Site,Carbonate Rock Landform,Intrusive Rock Landform,Detrital Rock Landform,Waterfall,and Volcanic Rock Landform,with a total of 21 important geoheritage sites.Conclusions:Through the evaluation of geoheritage sites in Hainan Tropical Rainforest National Geopark,there are 1 world-level geoheritage site,17 provincial-level geoheritage sites,and 3 sub-provincial-level geoheritage sites in Hainan Tropical Rainforest National Park.We suggest incorporating the protection of geological relics into the National Park protection planning system,and the utilization of geoheritage sites should be be integrated with the reality of the National Park.
