Investigation And Development Suggestion Of Geoheritage In Jiangshan GSSP Nature Reserve,Zhejiang Province

Protected areas are designed to protect those natural relics of special significance,focusing on protection,while the establishment of national parks is to pay equal attention to scientific protection and rational development.The geopark is a unique natural area of the site constructed by integrating natural and human landscapes with geological relics with special geological significance and high aesthetic value as the main body.After the Jiangshan “GSSP” Reserve was approved by Jiangshan City as a provincial-level geoheritage nature reserve in 2015,the local government is also making preparations for the declaration of a geopark.The Jiangshan "GSSP" Reserve in Zhejiang Province is centered on the "GSSP" geoheritage,and there are other rich,diverse and extremely valuable geoheritage around the reserve.(1)The Jiangshan "GSSP" is the stratotype profile and point of the global chronostratigraphic unit boundary of the Cambrian Jiangshanian,which means it has extremely high scientific research value and outstanding global comparative significance;(2)The karst landform of the Shuangta Stone Forest Scenic Area is uneven,diverse in shape,and highly ornamental."Underwater world" is an extremely appropriate adjective for its landscape;(3)The stromatolites not only have the significance of dividing and comparing the evolution of stratigraphy,geography,biology,environment and extinction rules in a certain area,but also have high ornamental value.The cone stromatolites in the reserve are the most distributed in the upper Xifengsi Formation in this area.wide type;(4)The lithology of the Leigongwu Formation is dominated by moraine conglomerates,and the samples were collected through paleomagnetic studies.The moraine in this area provides a new basis for the theory of "Snowball Earth";(5)As a modern relic transformation of the research area,the mine relics can better respond to the response of "lucid waters and lush mountains are invaluable assets",and provide some modern cultural atmosphere for the planning and construction of the Geopark.First,this paper summarizes the natural geographical background and the socio-economic profile of the regional geological and environmental relics of the Jiangshan "GSSP" protected area.On the basis of field investigation,the geoheritage resources in the reserve have been classified completely and systematically.Secondly,use quantitative evaluation and qualitative evaluation to evaluate the main geological relics in the protected area,and according to the evaluation results and the feasibility analysis of the construction of the protected area,on the basis of following the guidelines and policies of the national and local protected area planning,the site is carried out.The plan is divided into five major geoheritage scenic spots with the GSSP reserves the core area.According to the geological significance of the formation of each geoheritage,a specific plan for the construction of protected areas is given,which is beneficial to the protection of Jiangshan geoheritage and the local economy development of.
