新型冠状病毒肺炎疫情爆发为我国传染病防控治理带来了严峻的挑战。绿地是城市中最具弹性的公共空间。为促使其防控效能的高效发挥，在梳理重大公共卫生事件下绿地防灾避险规划现存问题和发展趋势的基础上，探讨了城市绿地在应对疫情时承担的防御、减缓、治理等作用，并从城市级、区级、社区级 3 个空间尺度提出了城市绿地防控单元的规划策略，形成了“平疫结合”的运行管理机制，以期在城市内建立“网络 + 点状”的绿地防控单元体系，有效组织城市绿地与其他防灾空间，减少城市非常时期的人员伤亡及财产损失。

The outbreak of the new crown epidemic has brought severe challenges to the prevention and control of infectious diseases in China. Green space is the most flexible public space in the city. In order to promote the efficient use of green space prevention and control effectiveness, this article discusses the role of urban green space in defense, mitigation, and governance in response to the epidemic based on the existing problems and development trends of the green space disaster prevention and avoidance plan under major public health incidents. In addition, a planning strategy of the urban green space prevention and control unit is proposed from the three spatial scales of city level, district level and community level, forming an operation and management mechanism that combines normal and epidemic prevention, in order to establish a “network + point-like” green space prevention and control unit system in the city, effectively organize urban green space and other disaster prevention spaces, and reduce casualties and property losses in the city during emergency periods.
