Study on Spatial layout and Environmental Equity of Urban green Space in Nanning City based on GIS

Abstract

Urban green space plays a vital role in urban environment. The research finds that at present, the domestic focus of urban green space is mainly focused on the internal relationship between economic, social and spatial change, but there is still a lack of attention to its impact on environmental equity. In this paper, taking Nanning City as an example, the kernel density estimation method is used to evaluate the impact of urban green space on environmental justice based on the analysis of the characteristics of urban green space layout, and explore its causes. The results show that the distribution of green space in Nanning is characterized by "overall dispersion, local concentration, more in the north and less in the south". There are deficiencies in the spatial distribution equilibrium of green space resources in the main urban area and the level of per capita access to green space resources, and the service level of green space needs to be improved.
