摘  要:Deeply integrated vulnerability and its evaluation framework provide a new perspective for the study ofsocio-ecological systems in metropolitan suburbs.A new vulnerability evaluation system of‘exposure-sensitivityadaptability’based on the socio-ecological system and vulnerability theory was constructed.Meanwhile,drawing onthe concept of‘spatial trap’,the concept of‘spatial vulnerability trap’was tried to put forward.The spatial-temporal interaction characteristics were analyzed,the existence of spatial vulnerability trap was tested and the interactionmechanism of vulnerability dynamic evolution was revealed using spatial-temporal exploration analysis method andgeographic detector for socio-ecological system vulnerability of 184 administrative villages in Qingpu District from theyear 1998 to 2018.The results showed that:(1)During the study period,the socio-ecological systems vulnerability ofQingpu District increased from 0.518 to 0.621,and the vulnerability level increased from low grade to medium grade.The spatial-temporal pattern showed the dynamic characteristics of first increase and then decrease and high in theEast and low in the west.(2)The relative length of the socio-ecological systems vulnerability temporal path movementin Qingpu District from 1998 to 2018 showed a trend of gradual decline from the central region to the surrounding area.The mobility curvature of the vulnerability time path was relatively small,showing the spatial pattern of low in the northand high in south,and the cohesion index of the spatial transition of vulnerability is 0.496.The spatial agglomerationstructure had relatively high transfer activity and low path locking.(3)No‘spatial vulnerability absolute trap’was detected during the study period,yet the‘spatial vulnerability relative trap’highlighted in the 11 administrative villagesmainly distributed around the administrative boundary in the north and south of the area.(4)Social capital factor,human capital factor,social factor,economic factor,ecological factor 深度融合脆弱性评估框架为都市郊区社会-生态系统研究提供了新的视角。研究基于社会-生态系统和脆弱性相关理论构建了“社会-经济-生态—敏感性-适应性”的脆弱性评价体系,借鉴“空间陷阱”理念,尝试提出了“空间脆弱性陷阱”概念,采用时空探索分析法和地理探测器分析了1998-2018年上海青浦区184个行政村社会-生态系统脆弱性时空交互特征,检验了空间脆弱性陷阱存在性和揭示了脆弱性动态演变的交互影响机制。结果表明:(1)研究期间青浦区社会-生态系统脆弱性指数由0.518增长至0.621,脆弱性等级由中低等脆弱提升至中等脆弱;时空格局呈“先增后降波动式”和“东高西低团聚式”的动态特征。(2)1998-2018年青浦区社会-生态系统脆弱性时间路径移动相对长度呈现由“中部区域向四周逐渐递减”的变化趋势,脆弱性时间路径移动弯曲度较小,呈现“南北部高中部低”的空间格局,脆弱性时空跃迁的凝聚指数为0.496,空间集聚结构存在相对较高的转移活性和较低的路径锁定性。(3)研究期间没有检测到“空间脆弱性绝对陷阱”,但“空间脆弱性相对陷阱”凸现,主要分布在该区的北部和南部行政界线周边的11个行政村。(4)社会资本因子、人力资本因子、社会因子、经济因子、生态因子和金融资本因子是影响脆弱性变化的主要因子,但各因子影响力呈现波动变化和类型差异;内外耦合性累积型、内生性能力约束型和外生性环境胁迫型是导致都市郊区社会-生态系统脆弱性分异的主要交互影响类型。研究结果对指导都市郊区防范脆弱性风险、促进区域协同、降低脆弱性和可持续发展具有重要的理论意义和实践价值。
