Characteristics And Evaluation Of Geological Relics Resource Of Debris Flow National Geopark In Dongchuan,Yunnan Province

Geological relics are valuable assets formed by the interaction of the internal and external forces of the Earth for a long time.We can study the geological relics to invert the historical evolution of the atmosphere,the lithosphere,the soil circle,the hydrosphere,and the biosphere [1-3].Debris flow is regarded as a kind of geological disaster in people's conventional impressions.However,by looking at the debris flow from another angle,it is a spectacular geological relic.It can protect the geological relics and carry out the science,popular science education and aesthetics of debris flow geological relics.Appreciation and tourism development.This paper is based on the planning and reporting of the Dongchuan Debris Flow Geopark and carries out research projects.The geological relics in the debris flow geological park in Dongchuan,Yunnan Province were evaluated for geological relics.The geological relics in the park were classified and described according to the characteristics of the geological relics.The geological sites were evaluated qualitatively and quantitatively,and the geological park was obtained.Has high scientific value,popular science value,aesthetic value and many other aspects.The research content of this article mainly includes 4 parts:First,through the collection of literature data,the DEM data was used to extract the topographic factors such as slope,aspect,elevation,and undulation in the Dongchuan District,and the environmental geological background and formation conditions for the formation of geological remains in Dongchuan District were basically understood.Formation process.Second,through the preparation requirements of the “National Geological Park Planning and Formulation Technical Requirements”(Guozi Zifa [2016] No.83)prepared by the Ministry of Land and Resources,and combining the above-mentioned secondary development of the data and field field investigations,the Dongchuan Debris Flow Geological Park is divided.Relic type and sub-category.Thirdly,by means of remote sensing technology and field trips,the typical characteristics of the geological relics in the debris flow geological park in Dongchuan were described,and the relationship between the spatial distribution and spatial distribution of geological relics within the park and the geological environment background was ascertained.Fourth,qualitative and quantitative evaluation of the scientific value,scientific value,aesthetic value,typicalness,completeness,and historical and cultural value of the geological relics in the park will be carried out to determine the level of the park and whether it will meet the national geology.Park establishment standards.
