The COVID-19 pandemic has exposed inequalities that are expected to widen if no action is taken to support the most marginalized populations. One such inequality is the distribution of urban green spaces (UGS), which are essential to pandemic recovery. Cities that aim to be inclusive and resilient should assess whether access to their UGS is equitably distributed among the population and identify the areas where these spaces are most needed. This study therefore examines the equity of access to UGS in Mexico City at the neighborhood level using network analysis. First, access to UGS was identified at a threshold of 300 m, regardless of UGS size. Second, access was differentiated by the functional level of the UGS, which primarily depends on their size, with larger UGS having more extensive catchment areas. The results of this study suggest a deficit of access to small green spaces in most of the neighborhoods of Mexico City, with the neighborhoods with higher rates of poverty showing an even lower average of UGS access. The results further highlight which neighborhoods in Mexico City should receive priority attention and funding for UGS to mitigate the disproportionate effects of public health crises. This is critical for future city planning and may be used as a roadmap for identifying priority neighborhoods in other cities with similar segregation patterns.
新冠疫情暴露了各种不平等现象，如果不采取行动支持最边缘化人群，这些不平等预计还会加剧。城市绿地（UGS）的分布不均就是其中之一，而城市绿地对疫情后的恢复至关重要。旨在实现包容性和韧性的城市应评估其城市绿地的可达性在人口中是否公平分布，并确定最需要这些绿地的区域。因此，本研究使用网络分析方法，在社区层面考察了墨西哥城城市绿地可达性的公平性。首先，无论城市绿地大小，确定在300米阈值范围内的城市绿地可达性。其次，根据城市绿地的功能水平对可达性进行区分，城市绿地的功能水平主要取决于其规模，规模较大的城市绿地集水区范围更广。本研究结果表明，墨西哥城大多数社区的小型绿地可达性不足，贫困率较高的社区城市绿地平均可达性更低。研究结果进一步凸显了墨西哥城哪些社区应在城市绿地方面获得优先关注和资金，以减轻公共卫生危机造成的不均衡影响。这对未来的城市规划至关重要，可作为识别其他具有类似隔离模式城市中的优先社区的路线图。
