Study On The Value Evaluation And Protection Of Geological Relic Landscape

As a unique natural resource on earth,geological relic landscape has its unique characteristics different from other resources.Scientific and quantitative evaluation method is an important prerequisite for its rational protection and utilization.Internationally,the evaluation of geological heritage landscape has developed towards the direction of refinement,digitalization and digitalization,such as the map evaluation method combined with GIS by ENVI,SPSS and other multi-disciplinary technologies,and the landscape preservation evaluation method.The evaluation of geological heritage landscape in China is mainly based on the single discipline,which is mainly qualitative or quantitative evaluation based on questionnaire.In the era of diversified data acquisition channels and the emergence of new technology and methods,the geological relic landscape should use scientific and reasonable evaluation methods to enhance the practical significance of resources in the protection and utilization.This papaer based on network reviews,big data and remote sensing image as the main data base,with multidisciplinary technology such as geography,statistics and GIS platform coupling model build,make innovative research from the following three aspects: 1.on the basis of large data of crawl,build our above province level of geological relics landscape geospatial database;2.Classified the value types of cases in the database by combining the quantitative analysis method of multiple correspondence;3.Under the guidance of value classification,quantitative evaluation was carried out on jixian national geo park from four aspects including scientific research value,ecological value,natural aesthetic value and tourism use value,and an evaluation system of "value explanatory variable" was established.There are five parts in this thesis: the first part is basic research.By using the bibliometric visualization analysis of Citespace,the research hotspots,thematic word frequency and research trends of the geological relic landscape in the field of evaluation and protection at home and abroad are summarized,and the related theories and evaluation methods are summarized.The second part is value classification.Using multiple corresponding quantitative analysis method for large data crawl over the level of provinces and cities in our country comprehensive value of geological landscape resources classification,and it is concluded that geological relic landscape value evaluation of the four major branches,namely the research in terms of resource conservation value and ecological value,in the use of resources of natural aesthetic value and use value.The third part is value evaluation.Based on the coupling model of multi-disciplinary technology and GIS platform,this paper quantitatively evaluates the research value,ecological value,natural aesthetic value and tourism use value of the geopark in jixian national geopark,and establishes the evaluation system of "value explanatory variable".Part iv protection and utilization research.Based on the value evaluation results,this paper puts forward the optimization strategies for the geological heritage landscape in the study area from the aspects of resource protection and utilization,and puts forward the resource adjustment strategies in combination with the world geopark evaluation standards.The fifth part is conclusion and prospect.This paper summarizes the conclusions on the classification,evaluation and protection of geological heritage value,and prospects the research deficiency and development direction.
