标题： Schoolyard Greening, Child Health, and Neighborhood Change: A Comparative Study of Urban U.S. Cities

摘要： 背景：校园绿化已成为一种创新方法，用于改善美国城市儿童的健康和环境公平性。 然而，对邻里动态和社会公平的影响尚不充分了解。 方法：这项比较文献综述综合了同行评审研究和主要美国城市校园绿化的案例分析中的定量和定性证据。 结果：校园绿化持续增加了使用率，并对儿童的身体活动和幸福感有积极但变化的影响。 然而，这些好处并不总是公平分配，绿化项目可能会促进邻里变化，有时导致绿色拆迁。 结论：绿化城市校园对儿童健康和城市可持续性有益，但对公平和社会正义提出了挑战。 政策必须优先考虑包容性的、以社区为主导的方法，以确保绿化的好处被弱势群体共享。 显示英文摘要

摘要： Background: Schoolyard greening has emerged as an innovative approach to enhancing childrens health and environmental equity in urban U.S. cities. Yet, the implications for neighborhood dynamics and social equity are insufficiently understood. Methods: This comparative literature review synthesizes quantitative and qualitative evidence from peer reviewed studies and case analyses of schoolyard greening in major U.S. cities. Results: Schoolyard greening consistently increases utilization and has a positive, though variable, effect on childrens physical activity and well-being. However, the benefits are not always equitably distributed, and greening projects can catalyze neighborhood change, sometimes leading to green gentrification. Conclusions: Greening urban schoolyards offers benefits for childrens health and urban sustainability but poses challenges for equity and social justice. Policies must prioritize inclusive, community driven approaches to ensure the gains of greening are shared by vulnerable populations.
