Green space equity: spatial distribution of urban green spaces and correlation with urbanization in Xiamen, China

With the progress of urbanization, the living rhythm of urban residents has become faster and more stressful. The role of the natural environment in relieving the stress of urban residents has become more important in cities. As urban green space (UGS) is the most accessible natural environment for urban residents, the rationality and equity of its distribution are particularly emphasized nowadays. In this research, Xiamen had been used as an example to analyze the relationship between the level of urbanization and the equity of UGS services. This research found: (1) polarization in urbanization of the inner city and outer city, and inequity in the distribution of urban green spaces in Xiamen. (2) The urbanization level and distribution of UGS demonstrated a radial mode that gradually shrinks from inner city to outer city. (3) This research found a significant positive correlation between urbanization and UGS provision, and spatial heterogeneity in the spatial relationship between them. In order to coordinate future urban development and the planning of UGS service, this research suggests increased investment in infrastructure construction in outer city, and the government should consider a policy to encourage the population transfer from inner city to outer city, through the balancing of urbanization level and UGS service equity between inner and outer city to build a harmonious and sustainable green city.
