Evaluation of cultural ecosystems services of urban park from the perspective of tourists:a case study of Daming Lake Park in Jinan
Cultural ecosystem services(CES)are the link between human society and natural systems.The way perceiving and quantifying cultural ecosystem services through the use of social media networks is an effective method for decision-making and management of urban parks.Daming Lake Park in the World's First Spring Landscape was selected for the study.Web data such as social media texts,star ratings and photos are used as data sources.Machine learning models,kernel density analysis,correlation analysis and cultural service diver-sity analysis are used.The developmental evolutionary patterns of cultural ecosystem services are studied,the spatial distribution patterns of cultural ecosystem services are quantitatively identified,and the relevance and di-versity of cultural ecosystem services are assessed.The relevance and diversity of cultural ecosystem services are assessed.The results show that the pattern of cultural services for visitors shows an'increasing-decreasing-increasing'trend,with the distribution of cultural services perceived by visitors in the ecosystem in the following order:aesthetic＞recreation＞cultural diversity＞inspiration＞social relations＞spiritual and religions visitors'per-ceptions of different cultural services have different characteristics,and the overall distribution of cultural serv-ices is'trapezoidal';the correlation coefficient between recreation and social relations is the highest at r=0.69,followed by the correlation coefficient between social relations and cultural diversity at r=0.62,and the correla-tion coefficient between aesthetic services and recreation services at r=0.50.The diversity of cultural services at different points of interest varies significantly,and the diversity indexes of 28 points of interests are greater than 0.6.This shows the importance of optimising the planning and development of urban parks based on visitor per-ceptions and quantifying cultural ecosystem services.
