摘　　要：基于熵值法测度2011—2020年关中平原城市群11个地市的城市韧性综合评价指数,分析其韧性时空演化特征,并采用社会网络分析法和二次指派程序剖析其空间关联网络结构及影响因素。结果表明:(1)关中平原城市群内各城市韧性整体呈上升趋势,韧性水平呈现出从省会开始向外围降低的态势。(2)城市群韧性网络结构变得更加复杂和稳健,但地区间韧性联系呈现较强的层级性特征,也尚未完全实现互相联通的状态。(3)西安市、咸阳市、铜川市的中心性较强,能够对周边或边缘城市产生较多资源溢出,城市群“核心-边缘”结构明显。(4)地理空间邻近、经济发展水平、对外开放度、政府财政支持、科技发展水平、交通基础设施的差异均显著影响城市群韧性空间网络结构的变化。关中平原城市群可通过建设城际数字化管理与交流平台、加强交通网络建设、增加科技创新投入等途径提升城市韧性与城市间的关联性。This study constructed an urban resilience evaluation index system that included four dimensions:economy,society,ecological environment,and infrastructure.Based on the entropy method,the resilience com-prehensive evaluation index of 11 cities in the Guanzhong Plain urban agglomeration,northwest China from 2011 to 2020 was measured,and the spatiotemporal evolution characteristics of their resilience were analyzed,and moreover,the social network analysis method was used to analyze the structural and functional connections be-tween cities in the resilience network of the Guanzhong Plain urban agglomeration.Furthermore,the quadratic as-signment procedure was used to explore the comprehensive factors that affected the resilience network structure of the Guanzhong Plain urban agglomeration.The results indicated the following.(1)The overall resilience of each city in the Guanzhong Plain urban agglomeration was on the rise,and the resilience level showed a decreas-ing trend from provincial capital to the periphery.(2)The resilience network structure of urban agglomerations had become more complex and robust;however,the resilience connections between regions exhibited strong hier-archical characteristics and cities had not yet fully achieved interconnectivity.(3)Xi’an,Xianyang,and Tongch-uan had strong centrality and could generate significant resource spillovers to surrounding or peripheral cities.The“core-edge”structure of urban agglomerations was obvious.(4)The level of economic development,open-ness,government financial support,scientific and technological development,differences in transport infrastruc-ture,and geographical proximity all significantly affected changes in the resilient spatial network structure of the urban agglomeration.Therefore,to enhance the resilience of the Guanzhong Plain urban agglomeration and the connection between cities,one must first build an intercity digital management and exchange platform and pro-mote the diffusion of resource elements from high-to low-agglomeration areas.Second
