Justice Evaluation of Urban Green Space: A Case Study of Chaoyang District, Beijing

Following the socialized, human-oriented transformation of urban development, studies of the justice of urban green space have gradually gained attention. This research attempts to apply the views and principles of Rawls' Theory of Justice, along with the evaluation methods of public service facilities, to build an evaluation framework of urban green space justice. Taking Chaoyang District of Beijing as an example, it evaluates the justice in four aspects: freedom of rights, equal opportunities, spatial justice, and balanced supply and demand. The results show that: 1) There are large blind areas of green space services, which fail to meet the bottom line requirements of equal opportunities; 2) Green space resources also fail to prioritize socially disadvantaged groups, which has not met the requirements to favor the least beneficiaries; 3) The overall supply and demand relationship is relatively balanced, but it is urgent to solve the problem of high demand and low supply of local space. Based on the evaluation results, this paper puts forward three suggestions to vacate and add green to eliminate the blind areas of services, improve the friendliness of travel space, and improve the convenience of public transportation, so as to improve the justice of green space at all levels and provide reference for the relevant planning and construction of urban green space.
