摘　　要：为提升山地乡村社区灾害韧性评价的科学性与实践价值,文章基于PSR(压力―状态―响应)模型,融合熵值法与(AHP)层次分析法,构建了包含3个维度(压力韧性、状态韧性、响应韧性)、9个要素、32项指标的多层级评价体系,并以四川省凉山州安宁河流域的4个典型社区(桃源村、曹古村、牛郎村、群英村)为例,结合实地调研、GIS空间分析及多源数据进行实证研究。结果表明:1)社区综合韧性排序为桃源村>牛郎村>群英村>曹古村,桃源村因全国防灾示范社区建设,韧性最高,而曹古村因高海拔地形和基础设施滞后,韧性最低;2)状态韧性对总体韧性贡献度最高,其中C9村民住宅建筑质量为核心驱动因素,压力韧性中C2单侧距活动断层距离与C6地质灾害隐患点威胁人数显著影响风险等级,响应韧性依赖C26灾害监测设备与C27预警信息发布效率;3)基于“压力-状态-响应”协同优化路径,提出差异化防灾策略,包括风险区划与工程治理(压力层)、住房抗震改造与社会资本培育(状态层)、智慧预警与传统知识融合(响应层)。文章验证了PSR模型在山地乡村灾害韧性评价的适用性,揭示了“状态韧性主导、响应能力短板”的典型特征,为同类社区防灾规划提供方法论支持。To enhance the scientific rigor and practical relevance of disaster resilience evaluation in mountainous rural communities,this study developed a multilevel assessment framework based on the Pressure-State-Response(PSR)model by integrating the entropy method and Analytic Hierarchy Process(AHP).The framework comprised three dimensions(pressure,state,and response),nine elements,and 32 indicators tailored to the unique environmental and socioeconomic contexts of mountainous regions.Focusing on four representative communities(Taoyuan,Caogu,Niulang,and Qunying)in the Anning River Basin of Liangshan Prefecture,Sichuan Province,China,a combination of field surveys,GIS spatial analysis,and multi-source datasets were used to empirically evaluate community resilience.The key findings revealed the following:(1)The comprehensive resilience scores ranked Taoyuan>Niulang>Qunying>Caogu.Taoyuan's top performance stemmed from its designation as a national disaster prevention demonstration community featuring robust infrastructure and frequent emergency drills,whereas Caogu's lowest resilience resulted from its high-altitude topography,aging population,and inadequate infrastructure.(2)State resilience contributed most significantly to overall resilience(51.43%),with the building quality(C9)being the pivotal driver.Pressure resilience was predominantly influenced by the proximity to active faults(C2)and population exposure to geological hazards(C6),whereas response resilience relied on disaster-monitoring equipment(C26)and early warning efficiency(C27).(3)A synergistic optimization strategy was proposed,emphasizing risk zoning and engineering controls(pressure layer),housing retrofitting and social capital cultivation(state layer),and intelligent early warning systems integrated with indigenous knowledge(response layer).The study validates the applicability of the PSR model in mountainous rural contexts,highlighting a"state resilience dominance with response capacity gaps"pattern.Notably,communities with higher state resilience dem
