摘　　要：构建基于“规模—密度—形态”的三维流域生态韧性分析框架,运用耦合协调模型测算并分析2000—2021年汾河流域县域新型城镇化与生态韧性的耦合协调时空演变特征,采用空间自相关模型揭示耦合协调的空间集聚特征,引入协调影响力指数表征各子系统对整体耦合协调度的作用力及作用程度。结果表明:(1)2000—2021年汾河流域各县域新型城镇化水平总体缓慢提升,“核心—边缘”空间格局显著,生态韧性综合指数持续降低,空间格局上高值区呈“S”型分布,低值区集中于中部谷地。(2)耦合协调度呈现由“轻度协调”向“轻度失调”下滑的发展特征,受区位优势和生态禀赋因素影响,耦合协调度空间分布呈现由核心向边缘逐级提升的“环状”分布格局,空间集聚趋势显著。(3)新型城镇化中人口、空间、社会、绿色子系统对综合耦合协调度起反向阻滞作用,经济城镇化对综合耦合协调度的影响先阻滞后推动,生态韧性子系统对综合耦合协调度均起反向阻滞作用,规模、密度韧性阻滞力增强,形态韧性阻滞程度减弱。(4)新型城镇化水平不均衡发展的“马太效应”更加明显,生态韧性受制于生态资源本底,空间演变存在路径依赖现象,汾河流域兼具城镇化推进对生态产生负效应的流域普遍性特征和资源发展型县域产业转型缓慢、生态建设较城镇化显著滞后的特殊性。This paper constructs a"Size-Density-Morphology"basin ecological resilience evaluation system,using the coupled coordination model to estimate and analyze the spatial and temporal evolution characteristics of coupled coordination between new urbanization and ecological resilience in counties of the Fenhe River Basin from 2000 to 2021,and the spatial autocorrelation model is used to reveal the spatial clustering characteristics of coupled coordination.The coordination influence index is introduced to characterize the effect and the degree of role of each subsystem on the overall coupling coordination degree.The results show that:(1)From 2000 to 2021,the level of new urbanization in counties of the Fenhe River Basin had been improved slowly,the"core-edge"spatial pattern was significant,and the comprehensive index of ecological resilience had been decreasing continuously.The high-value areas in the spatial pattern are distributed in an"S"shape,and the low-value areas are concentrated in the central valley.(2)The coupling coordination degree is characterized by a downward trend from"mild coordination"to"mild imbalance".Affected by the location advantages and ecological endowment factors,the spatial distribution of the coupling coordination degree showed a"ring"distribution pattern of increasing from the core to the edge,and the spatial agglomeration trend is significant.(3)In the new urbanization,the population,space,society and green subsystems have a reverse blocking effect on the integrated coupling coordination degree,while the influence of economic urbanization on the comprehensive coupling coordination is first blocked and then promoted,and the ecological resilience subsystem has a reverse blocking effect on the integrated coupling coordination degree,with the scale and density toughness blocking increased and the morphological toughness blocking degree weakened.(4)The"Matthew effect"of the unbalanced development of new urbanization level is more obvious,and the external supply of energy in resource-based count
