The distribution of urban ecosystem services (UES) is often uneven across socioeconomic groups, leading to environmental justice issues. Understanding the distribution of UES across a landscape can help managers ensure an equitable distribution of services. While many past studies have focused on the distribution of green spaces in relation to socioeconomic variables, this research analyzes the distribution of UES provided by these green spaces. This research quantified air pollution removal, atmospheric carbon reduction, and surface runoff mitigation provided by urban trees in Strasbourg city (France). The provision of these three UES was studied at the census block scale by creating an index of UES delivery, which was contrasted with a constructed social deprivation index. Our results show that there is no significant association between the delivery of UES and social deprivation. Some deprived populations benefit from high UES delivery. Results also suggest that mapping associations between UES delivery and social deprivation should be integrated with future development plans to enhance the equitable distribution of UES. This study provides insights into the French context where studies about the distribution of UES at a small-area level remain lacking.

城市生态系统服务（UES）在不同社会经济群体中的分布往往不均匀，从而导致环境正义问题。了解 UES 在整个环境中的分布可以帮助管理者确保服务的公平分配。虽然过去的许多研究都集中在与社会经济变量相关的绿色空间的分布上，但本研究分析了这些绿色空间提供的UES的分布。这项研究量化了法国斯特拉斯堡市城市树木所提供的空气污染消除、大气碳减排和地表径流减缓作用。通过创建 UES 交付指数，在人口普查区块范围内研究这三种 UES 的提供情况，并将其与构建的社会剥夺指数进行对比。我们的结果表明，UES 的提供与社会剥夺之间没有显着关联。一些贫困人口受益于高 UES 交付。结果还表明，绘制UES交付与社会剥夺之间的关联应与未来的发展计划相结合，以加强UES的公平分配。这项研究提供了对法国背景的深入了解，法国目前仍缺乏有关小区域 UES 分布的研究。
