Research On Landscape Characteristic And Protective Development Of Earthquake Vestige Of Qingchuan National Geological Park

The National Geopark of the Qingchuan earthquake site is the most abundant and most concentrated earthquake site group in the Wenchuan earthquake,which is the first geological park to reflect the remains of the earthquake in the Wenchuan earthquake.The landscape of the park has a great value in scientific research,science and aesthetics,but after 10 years of development,the protection and development of the earthquake remains are facing some new problems.This paper,taking the landscape of the earthquake relics in the park as the research object,classifying and evaluating the landscape of earthquake relics,proposed a series of measures for the protection development of the seismic relics in the research area,and explored the road for the sustainable development of the Qingchuan Geopark.On the basis of previous studies,this paper takes full consideration of the causes of earthquake relics and landscape features,and divides the seismic traces into 2major categories,4 main categories,8 subcategories and 16 basic types.On this basis,the landscape in the study area is classified,and the typical landscape characteristics and causes in the area are systematically analyzed.On this basis,the evaluation index system is built by the analytic hierarchy process(AHP),and then the weight of each factor evaluation index is determined by the expert questionnaire.According to the actual situation of the earthquake relics in the research area,the scoring rules and methods are formulated,and the quantitative evaluation of the seismic traces in the region is made,and the result is the East estuary.The landslip debris flow relics and the East estuary Lake ruins landscape are the key seismic relics landscape.The protection development in the park should focus on the protection of the two landscape points.Secondly,the landscape conditions of the landslides and debris flow sites in the Ma Gong township are divided into second of all the landscape points,but the development conditions are the lowest,because the development conditions are the lowest.The landscape point is of great potential for development.Finally,according to the current situation and existing problems of the protection of earthquake relics,this paper breaks the traditional static research mode,takes human and earth harmony as the core,and sets up corresponding dynamic response measures according to the development and evolution process of earthquake disaster events,and puts forward the protective development mode of "one nuclear and three axis" earthquake relics landscape.That is,taking the landscape of earthquake relics asthe core point and the harmony between human and land as the starting point,according to the different periods after the occurrence of the earthquake events,the space layout and the development of landscape resources have been put forward in different periods,so that the protection measures and the protective development measures complement each other.
