Spatial Matching of Supply and Demand for Multiple Cultural Ecosystem Services in Park Green Spaces:A Case Study of the Main Urban Area of Chengdu
Analyzing the supply and demand matching characteristics of cultural ecosystem services(CES)in rapidly urbanizing regions is important for sustainable urban development.However,comprehensive identification of the matching characteristics of the supply and demand of multiple CES in urban park green spaces is difficult in existing studies.Therefore,in order to identify the differences between multiple CES supply,residents'diversified demands and actual service,this study takes the main urban area of Chengdu as an example and combines data analysis,social survey and spatial analysis methods to evaluate the spatial differences of actual service,potential supply and potential demand of six CES(recreation,aesthetics,socialization,exercise,culture and inspiration)of park,analyzing the supply and demand clustering characteristics.The results show that:1)The overall distribution shows that the actual service shows the distribution of high in the northeast and low in the west;the potential supply shows the distribution of high in the south and low in the north and east;the potential demand shows the distribution of high in the middle and low around;2)The spatial distribution of supply and demand matching shows that services show a shift from supply redundancy to supply deficit from the border to the city center.The CES mismatch area accounts for 85％of the study area,among which,inspiration＞aesthetics＞entertainment=culture＞exercise＞social;3)On the clustering of supply and demand,high supply-low demand accounts for the largest proportion,37％,and low supply-high demand is distributed in the central part of the study area,20％.This study evaluates the supply-demand matching of multiple CES in urban parks and provides a rigorous basis for urban green space system planning.
