明确社区韧性定义中蕴含的经典内涵，提出重大传染病疫情社区韧性的定义，准确界定其内涵外延，为提高社区应对重大传染病疫情的能力提供理论支撑。

在Rodgers演化概念分析法的指导下，系统检索国内外社区韧性定义研究相关文献，全面收集社区韧性定义；使用文献计量法，计算社区韧性定义的影响力指数并排序；使用内容分析法解析社区韧性定义的内涵；使用共词聚类分析法归纳出经典内涵，并明确其重要性序位；运用形式逻辑学中最公认的概念界定方法"属+种差"法，结合重大传染病疫情特点和防治策略，对重大传染病疫情社区韧性进行初步定义，并开展两轮专家咨询，对定义修改完善。

检索19 092篇文献，纳入411篇，共筛选收集63个社区韧性定义，解析得到228条内涵，聚类分析得到16个经典内涵；按照"对象、组织形式、手段、过程、任务、结果、目标、价值、影响因素"的逻辑顺序，提出了重大传染病疫情社区韧性的定义，并界定其6个内涵与2个外延。修改完善后的定义专家认同率达到100.00%。

重大传染病疫情社区韧性定义为：面对重大传染病疫情时，社区在政府部门主导、社区协调、志愿者参与、社区成员配合下，有效利用各种资源，做到事前正确预测预警，对可能发生的疫情做出预防和应急准备，事中快速反应抵御疫情，事后迅速有效恢复社区正常运行并从中吸取经验教训，进而降低疫情影响，维持社区基本结构和功能，确保社区居民健康安全，社区业务和行政功能的可持续发展。

To clarify the classic connotation contained in the definition of community resilience, to put forward the definition of community resilience for serious infectious diseases outbreaks, and to accurately define its connotation and extension to provide theoretical support for improving the ability of communities to cope with major infectious diseases.

Under the guidance of Rodgers’ evolutionary concept analysis method, the relevant literature on the definition of community resilience at home and abroad was systematically searched, and the definitions of community resilience put forward by predecessors were comprehensively collected; Using the bibliometric analysis method, the impact index of the definition of community resilience was calculated and ranked; Content analysis was used to analyze the connotation of the definition of community resilience; the co-word cluster analysis was carried out to summarize the classic connotation and clarify its importance order; Using the most recognized concept definition method in formal logic, the "genus and species difference" method, combined with the characteristics and prevention strategies of major infectious diseases, the community resilience of major infectious diseases was initially defined. After two rounds of expert consultation, the definition was revised and improved.

A total of 19 092 documents were retrieved and 411 were included. A total of 63 definitions of community resilience were selected and collected. 228 connotations were analyzed and 16 classic connotations were obtained by cluster analysis. According to the logical order of "objects, organizational forms, means, processes, tasks, results, goals, values, and influencing factors", the definition of community resilience in serious infectious disease outbreaks was proposed, and six connotations and two extensions were defined. The expert recognition rate of the revised definition reaches 100.00%.

The community resilience of major infectious disease epidemic is defined as: when faced with major infectious disease epidemic, under the leadership of government departments, community coordination, participation of volunteers and cooperation of community members, the community effectively uses all kinds of resources to correctly predict and early warning in advance, makes prevention and emergency preparedness for possible epidemic situations, reacts quickly to resist the epidemic situation in the event, and effectively recovers the normal operation of the community after the event, and draws lessons from it, and then reduces the impact of the epidemic, maintains the basic structure and functions of the community, and ensures the health and safety of community residents and the sustainable development of community business and administrative functions.
