Abstract: Assessing the supply and demand of urban ecosystem services at the community scale is vital for enhancing urban ecological governance and management. Based on multi-source data such as remote sensing and land survey data, we quantified and mapped the supply and demand of air purification, temperature regulation, and recreational services at community level in Jiading District of Shanghai by applying relevant indicators and performing spatial analysis. The results showed that: (1) The supply of air purification, temperature regulation, and recreational services exhibited significant variations across community. The spatial patterns of different services were generally consistent, characterized by higher supply in the north and lower supply in the south of the district. (2) The spatial pattern of demand varied among the three aforementioned ecosystem services. The demand for air purification services was higher in the northern and southern regions and was lower in the central regions. The demand for temperature regulation and recreational services was higher in the southern and central urban areas and lower in the northern and surrounding suburban areas. (3) The overall ecosystem services of each community were at a state of mismatch between supply and demand, with the degree of mismatch between supply and demand for temperature regulation being the most serious. The match between supply and demand of the three types of ecosystem services generally showed a spatial distribution pattern of “superior in the north and secondary in the south, poor in the center and good in the periphery”, but there were certain discrepancies in the spatial distribution of supply and demand matching of the three ecosystem services. These findings can offer valuable insights for the spatial allocation, structure design, and management of ecological spaces, ultimately meeting the demands of urban residents for a pleasant living environment.
