摘要:

土地和房地产市场化背景下的公园绿地供给的公平 性研究具有重要意义。以重庆市中心城区为例，居住小区为研 究单元，从可达性、数量、面积和质量４个维度衡量不同价格 级别居住小区的公园供给的公平性。采用高德互联网地图分析 步行、公共交通２种方式下研究范围内4 663个居住小区的 公园供给的可达性、数量、面积和质量状况；非参数秩和检验 判别不同级别居住小区的公园供给差异。结果表明：不同级别 居住小区的公园供给未发现明显的不公平现象，低级别居住小 区在可达性、数量、总面积上占优势，人均公园面积低于高级 别居住小区，各级别居住小区在高质量公园的使用机会上没有 差异。本文所采用的公园绿地公平性定量评价方法，可为城市 绿色空间、公共服务设施绩效评价提供方法借鉴

Abstract:

In the context of land and real estate market, the study on the equity of park green space provision is of great significance. Using the case of Chongqing, regarding residential community as the research unit, this paper assessed the equity of park provision in residential communities of different price levels from four dimensions of accessibility, quantity, area and quality. The accessibility, quantity, area and quality were measured under two transport modes (walking and public transit) with the help of internet map. Rank sum test was used to analyze the difference of different levels residential communities' parks provision. The results show that the provision of park green space in different levels of residential communities has not been found to be significantly inequity. Low-level residential communities have an advantage in accessibility, quantity and total area, having a disadvantage in park area per capita than high level residential communities. There was no difference in opportunities of the use of high quality parks. The method used to assess the equity of park green space can provide a reference for the performance evaluation of urban green space and urban services.
