Research On Environmental Renovation Strategy Of Diaoyutai Site In Bengbu City Based On Multi-Subject Appea

The site refers to the remains of human activities,and the Diaoyutai site in Bengbu City is located in the central city,with a cultural layer presenting the Late Longshan to Shang and Zhou periods,which is of great significance to the study of ancient civilizations in the Huaihe River basin.Today,the Diaoyutai site has been built around a residential area,and the site is closely related to the lives of the surrounding residents.The traditional environmental remediation of the site is often government-led and fails to fully reflect the demands of multiple subjects;therefore,the environmental remediation strategy of the site is studied from the perspective of the demands of multiple subjects.First,Sorting through the relevant literature,elaborate the concepts related to multiple subjects and site environmental remediation,and integrate domestic and international research on site protection,site display,and synergistic development of sites and regions.Classifying sites in the central city in terms of time,material and function,analyze the characteristics of sites,the destruction factors they face and the content of environmental remediation,and analyze actual cases.Exploring the archaeological situation of the Diaoyutai site,grasp the site proper and excavated artifacts,and explain the regional environment,location,and value of the site,as well as the current status of protection and utilization of the Diaoyutai site and the need for environmental remediation of the site.Secondly,the multiple subjects of the Diaoyutai site were defined and classified,focusing on the demands of the core participating subjects,that is,the demands of the surrounding residents,local government and tourists.Questionnaires were conducted for the three types of core participating subjects separately,and factor analysis was conducted on the questionnaire data,using principal component analysis with variance maximization rotation to extract the main factors and clarify the different demand situations of core participating subjects.The common demands include site protection,site display and environmental benefits,while the different demands include participation,service to residents,tourism quality and site value acquisition.The current situation of the site has problems such as soil erosion,vegetation interference,insufficient road network,building encroachment,residents’ activities,and garbage pollution.Finally,the site image information is obtained by using the Unmanned Aerial Vehicle(UAV)tilt photography technology,loaded into Context capture Master software to construct 3D model,digital orthophoto(DOM),digital surface model(DSM),generate digital elevation model(DEM)by Terra Solid software,and import it into Arc GIS software for analysis to get site elevation,slope,slope direction,skyline,and viewable area results.Combining the common and different demands of multiple subjects of the site,the current problems and the results of 3D modeling analysis,the subjective demands and objective factors of the Diaoyutai site are considered,and the principles of authenticity,integrity,sustainability and participation of multiple subjects are upheld,proposing to protect the material form and continue the city’s cultural lineage;highlight the features of the site and show the historical value;strengthen the communication between multiple parties and plan the overall development;serve the surrounding residents and meet their daily needs;and to improve the quality of tourism and obtain the value of the site.
