    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, the study aims to determine how the functions and efficacy of protective green spaces can be fully utilized in response to sudden public health events. This study is driven by the observation of the 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 efficacy of protective green spaces be fully utilized in response to sudden public health events?
    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. The methodology includes four parts. 1) Risk Response Evaluation: Assessing the ability of protective green spaces to respond to risks, including evaluating their resilience levels and formulating pre-planned responses to public health events. This involves creating metrics for resilience and adaptability, ensuring that green spaces can provide critical services during emergencies. 2) Functional Enrichment and Expansion: Expanding the functional service elements of green spaces to cover both normal 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 the spaces. 3) Scenario Predictions: Proposing scenario predictions for both normal 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 how green spaces will perform under different conditions and ensuring that they can meet the needs of the population during both regular and crisis times. 4) Technical Strategy Summarization: Summarizing technical strategies for optimizing the efficacy of protective green spaces. This includes best practices and guidelines for designing, implementing, and maintaining green spaces that are resilient and effective in mitigating public health risks.
    Results The study has resulted in the construction of planning and strategic frameworks for protective green spaces that are suitable for new urban developments and capable of addressing sudden public safety events. These frameworks are designed to maximize the diverse functions of green space systems, ensuring that they can provide essential services in both normal and emergency situations. Key outcomes include three parts. 1) Resilient Green Space Designs: Development of green space designs that prioritize resilience and adaptability, ensuring that these areas can quickly respond to and recover from public health emergencies. 2) Functional Integration: Successful integration of normal and emergency functions within green spaces, making them versatile assets for urban safety and community well-being. These spaces are now better equipped to serve as emergency shelters, quarantine zones, and areas for health and recreational activities during regular times. 3) Policy and Planning Recommendations: Formulation of policy and planning recommendations that support the inclusion of protective green spaces in urban development plans. These recommendations advocate for the integration of green spaces into national land spatial planning systems, ensuring their construction and maintenance are prioritized in urban planning processes.
    Conclusion In conclusion, the construction of a more comprehensive and proactive urban safety protection system requires enhancing the emphasis on the effectiveness of protective green spaces within the urban green space system. This study underscores the necessity of integrating protective green spaces into the national land spatial planning system to ensure their practical implementation and effectiveness. By doing so, cities can better prepare for and respond to public health emergencies, providing safe, versatile, and functional spaces that contribute to the overall resilience and well-being of urban populations. This integration will not only enhance the immediate response capabilities of cities but also ensure long-term sustainability and livability, fostering healthier, safer, and more resilient urban environments.
