MODELLING SUPPLY-DEMAND RELATIONSHIPS OF PARK GREEN SPACE RECREATION SERVICE FROM THE PERSPECTIVE OF CITY DWELLERS

Modelling the relationship between supply and demand of recreational services for promoting the fair and reasonable layout of urban park green space is very important. Current research studies mainly take the aggregation area as the basic unit, which inevitably leads to the Modifiable Areal Unit Problem (MAUP). Also, more emphasis is placed on the demand side, ignoring the supply pressure of the supply side. To address this issue, we propose a research framework taking the basic supply area and demand area of recreation services as the research units, to measure the supply-demand relationship from the supply side and the demand side, respectively. The application of the framework in Xuchang city of China shows that, it is in line with the characteristics of residents' recreational activities and can avoid the MAUP in the study of the ecosystem service supply-demand relationship. In addition, the framework can effectively identify the park green spaces with excessive supply pressure or low utilization potential and the residential quarters with low accessibility, to provide a practical and effective decision-making basis for coordinating the supply-demand relationship. Our research provides a useful tool for the study of the supply-demand relationship of urban cultural services.
