城市绿色空间的公正性评价——以北京朝阳区为例

随着城市发展向社会化和人本化转变，城市绿色空间公正性的研究逐渐受到重视。试图基于罗尔斯《正义论》的观点和原则，运用公共服务设施的评价方法，构建城市绿色空间公正性的评价框架。以北京市朝阳区为例，从权利自由、机会均等、空间正义、供需均衡4个方面进行公正性评价。研究发现：1）目前存在较大面积的绿色空间服务盲区，未能达到机会均等的底线要求；2）绿色空间资源也未能优先倾向于社会弱势群体，尚未达到有利于最少受惠者的要求；3）总体供需关系较为均衡，但亟须解决局部空间存在的高需求低供给问题。根据评价结果，提出腾退增绿、消除服务盲区，提高出行空间友好性，改善公共交通出行便捷性3条建议，旨在提高绿色空间各层级的公正程度，并为城市绿色空间的相关规划建设提供参考。

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.
