Characteristics And Evaluation Of Geological Heritages Resources In Beijing

As a kind of typical geological and geomorphic features developed and preserved by various internal and external forces of geological action during the long geological and historical evolution process,It is the precious property of nature left to mankind.However,with the development of society,there is a phenomenon of damage or incomplete development in the process of exploitation and utilization of geological heritages.Therefore,it is urgent to accelerate the investigation and research of geological heritages so as to obtain a scientific method for the rational use and protection of geological heritages.In view of the above problems,this paper gives a detailed description of the location conditions,geological features and protection status of 50 geological relics in Beijing by consulting literature and related data.The evaluation model of geological heritage resources in Beijing is constructed,Finally,the following conclusions are drawn:(1)Through the reading of a large number of literature and the search and sorting of relevant information,the characteristics of 50 geological heritages in Beijing are described.The location of the 50 geological heritages,the status of protection and the traffic conditions are arranged in detail.It not only laid a foundation for later research,but also found out the bottom of these 50 geological heritages in Beijing.(2)In the selection process of the evaluation factors of geological heritage,the factors of the evaluation of geological heritage resources in Beijing are determined,including 14 factors under three categories: natural attributes,value attributes,development and protection attributes.(3)The evaluation system of geological heritage resources in Beijing is constructed.Through the method of factor scoring and weight determination.A comprehensive evaluation of 50 qualitative heritages in Beijing is made,and 50 grades of geological heritages are obtained.(4)After comprehensive analysis,50 geological relics in Beijing area are analyzed.There are 2 world-class geological heritages,8 national geological heritages,28 municipal geological heritages and 12 local geological heritages.Finally,according to the characteristics of the heritage and the evaluation results,some suggestions on the protection and utilization of geological heritage resources in Beijing are put forward.
