This article considers Xiamen's two districts as examples to help identify the supply and demand of green services by focusing on the spatial equity of green space in microregions. Based on network and concentration methods, the results show there are great differences in equity enjoyed by residents. The equity value of Tong'an is generally higher than that of Jimei district, and the value of the periphery of the central urban area is generally higher than that of the inner area. Jimei relies more on traffic facilities than Tong'an. This study finds that the carrying capacity of rail transit cannot be ignored in accessibility. By measuring under three travel modes, the distribution density of green space in Jimei and Tong'an is basically similar. The main reason why Jimei's accessibility perform better than Tong'an district is traffic. Based on the service coverage rate (C) and the recreation opportunity index (R), this article obtained the regional evenness index, and found the overall characteristics of "high in the south and low in the north."This study suggests differences in spatial performance at the micro level are often complex, and consideration of different explanatory variables such as population may provide directions for policymaking.
