Spatial equity analysis of urban green space from the perspective of balance between supply and demand: A case study of Futian District, Shenzhen, China.

Abstract

Urban green space is an important ecological landscape, whose spatial distribution plays a significant role in improving the eco-environment and people's living quality. This study was initia-ted from the perspective of supply and demand balance to evaluate the equity of distribution of urban parks, drawing on previous research, and introduced an integrated framework for evaluating the equity of urban public facilities using spatial multi-analysis. A method concerning gravity model to assess the equity of urban green space was introduced, taking the effect of boundary into account. The case study area was the Futian District of Shenzhen and its 2000 m buffer area. Then, some optimizations were suggested for better allocation of the green space. The results showed that the equity of Futian District was low. The equity of community parks was lowest, followed by that of regional parks, while the countryside ecological parks owned the highest equity. About 50% of the Futian district area was in a state of balance between supply and demand and the rest were in a state of insufficient supply. Greening rate and space allocation of parks and road traffic systems should be improved to better plan the green space in Futian District. For urban green space planning, the parks of small area should be paid more attention to meet the needs of residents for daily recreation. By taking the effect of boundary into account, we observed that the residential area on the edge of the study area could enjoy the park green space, and the green space in the boundary area outside the region would be also shared by residents on both sides of the administrative boundary.
