摘要

Urban green spaces can promote physical activity, well-being, and public health, but disparities in the distribution of such spaces predominantly benefit affluent communities. Therefore, green justice issues have become a focus of academic research. In this paper, we develop a new model, the comprehensive floating catchment area (CFCA), to measure the accessibility of urban green space. The CFCA models urban green space attractiveness as a function of park size and of street green views from residential zones to parks. Three transportation modes (walking, biking, and driving a car) are compared. We take the central urban area of Beijing as the research area and measure green justice across different economic residential zones using the ordinary least squares model. The results suggest that the spatial disparities of urban green space are significant when only polygon urban green spaces are considered, regardless of the transportation mode. However, green injustice is mitigated when we consider both urban green spaces and street greening. To the best of the authors' knowledge, this is the first attempt to study green justice by taking a street green view, and the results of this study can provide guidance on urban green space development for government leaders and researchers in the future.
