摘　　要：【目的】通过分析公共卫生事件发生期间防护绿地防灾功能的短板,探究城市化快速发展进程中防护绿地功能需求的演变,提出发挥防护绿地功能与效用的策略,有助于提升城市的公共安全和风险应对能力,为城市规划者和决策者提供实践指导。【方法】1)提升防护绿地应对风险的能力,包括评估防护绿地韧性水平、构建基本防灾单元、优化生态系统服务功能;2)拓展防护绿地的功能服务要素,覆盖平时服务功能与灾时服务功能;3)根据防护的时效原则,对平时、灾时2个时期的情景进行预判,实施弹性调控。【结果】构建了适合中国绿地系统规划编制的防护体系功能提升与布局优化方法,从而发挥绿地系统的多元功能,应对突发公共安全事件。【结论】在建设更完备积极的城市安全防护系统中,需提高对城市绿地系统中防护绿地时效的重视程度,使防护绿地真正成为城市防灾体系的一部分,并纳入国土空间规划编制体系,确保防护绿地的建设能够切实实施。[Objective]The purpose of this research is to address the evolving demands for protective green spaces in the context of rapid urbanization and public safety.By analyzing the relationship between pandemics,societal organizational forms,and the response of the public health industry and landscape architecture discipline to risks,the research aims to determine how the functions and utility of protective green spaces can be fully utilized in response to public health emergencies.The research is driven by the observation of shortcomings in the protective and disaster-preventive functions of green spaces during public health emergencies,prompting a reevaluation of the role and necessity of these spaces in modern urban settings.The core research question is:How can the functions and utility of protective green spaces be fully utilized in response to public health emergencies?[Methods]The research employs a multi-faceted approach to analyze the underlying reasons for the inadequate attention to protective green spaces in academia and practice.This approach includes four parts.1)Risk response evaluation:Assess the ability of protective green spaces to respond to risks,including assessing their resilience levels and formulating pre-planned responses to public health events.This involves creating metrics for resilience and adaptability to ensure that green spaces can provide critical services during emergencies.2)Functional enrichment and expansion:Expand the service function elements of green spaces to cover both regular and emergency scenarios.This includes integrating multifunctional services that can be adapted for various uses depending on the situation,thereby enhancing the overall utility of green spaces.3)Scenario predictions:Propose scenario predictions for both regular and emergency periods to develop suitable planning and compilation methods for protective systems within China’s green space systems.This involves creating detailed models and simulations to predict the performance of green spaces under different
