With the development and progress of social civilization,scientific protection and utilization of scenic spots has become an important issue of national and regional development.As an important type of nature reserve system,scenic spots are an important carrier of ecological resources and the key content of practicing the construction of ecological civilization.Scenic areas are not only rich in natural resources,but also rich in human resources.Scientific and objective assessment of the social value of ecosystem services has important practical significance for the comprehensive grasp and effective use of the ecosystem services of scenic areas and the rational protection and utilization of various types of landscape resources.Yuelu Mountain Scenic Area has various landscape types and rich cultural resources.Based on the SolVES model and the network text data,this paper evaluates the social value of ecosystem services of the foothills scenic area,and analyzes the relationship between the environmental factors.(1)A total of 1 98 1 social value points were obtained.The order of importance of social value points was as follows:aesthetic value>existing value>entertainment value>therapeutic value>spiritual value>biodiversity value>life sustainable value>economic value>future value>scientific research value.(2)The core density of scenic spots shows that the social value points are mainly distributed in Aiwan Pavilion,Chuanshipo Lake,Yunlu Palace,Gulushan Temple,Yuelu Academy,sightseeing corridor,ropeway slideway along the road and other areas.(3)Network big data research shows that Aiwan Pavilion,Yunlu Palace,Gulushan Temple and Yuelu Academy are the most popular scenic spots in Lushan Scenic Area;Activities such as taking slides and cableways,taking photos and watching the sunrise are the most popular tourist(4)The social value of scenic spots is closely related to their elevation,distance from roads and distance from water bodies.From the model,we know that with the increase of height,tourists feel higher aesthetic value and therapeutic value.The farther the distance from the road,the fewer the signs of various social values for tourists,and the lower the value index.The distance from the water body shows a larger fluctuation,indicating that the location close to the water body,ornamental,entertainment,spiritual and so on have a greater feeling for tourists.(5)ROC curve and area of correlation curve(AUC)showed that the AUC values of six social values(aesthetic value,entertainment value,existing value,spiritual value,biodiversity value and therapeutic value)were all more than 0.7,which indicated that the evaluation results of SolVES model construction in this study had high reliability and certain practical application value.This study makes full use of the network big data to improve the SolVES model of the original questionnaire data to obtain the lack of unity,to a certain extent,improve the scientific objectivity of social value assessment of ecosystem services in Yuelu Mountain Scenic Area,and provide an effective case reference for related research and practical work.
