【摘要】 提升城市群生态韧性是生态城市建设的重要基石和关键举措。文章以长江中游城市群31个地级市为研究对象，基于韧性演化理论构建生态韧性评价指标体系，运用熵值TOPSIS法测算了各地级市2011—2022年的生态韧性值，考察了生态韧性的时空演变趋势及影响因素。结果显示：(1)在时间维度上，长江中游城市群生态韧性呈现出“波动起伏但整体上升”的发展态势。(2)在空间维度上，长江中游城市群生态韧性由西向东展现出“低—中—高”的三阶递进分异格局，这种空间差异主要源于区域内和区域间的交互作用。(3)在影响因素方面，公园绿地面积、工业固体废物综合利用率、人均水资源量、人均绿地面积和环保占财政支出的比重是制约长江中游城市群生态韧性的主要因素。由此，各城市要加强跨区域环保机制建设、统筹安排全域资源、“对症下药”破除障碍，以促进区域协调发展和社会和谐进步。更多还原

【Abstract】 Improving the ecological resilience of urban agglomeration is an important cornerstone and key measure of eco-city construction. Based on the evolutionary resilience theory, the article takes the 31 prefecture-level cities in the urban agglomeration of the middle reaches of the Yangtze River as the subjects and constructs an ecological resilience evaluation index system for the urban agglomeration of the region. The entropy-TOPSIS method was used to measure the ecological resilience of 31 cities from 2011 to 2022. The spatial and temporal evolution trend of ecological resilience was investigated. The results show that: 1) From the time dimension, the overall ecological resilience of the Yangtze River middle reaches urban agglomeration shows a “fluctuating but generally rising” development trend.2) In terms of the spatial dimension, the ecological resilience of the Yangtze River middle reaches urban agglomeration exhibits a three-tiered spatial distribution pattern of “low-medium-high” from west to east, and this spatial difference is mainly due to the mutual influence and interaction within and between regions. 3) In terms of obstacle factors, park green area, the comprehensive utilization rate of industrial solid waste, per capita water resources, per capita green space area, and the proportion of environmental protection to fiscal expenditure are the main constraints on the ecological resilience of the area in the middle reaches of the Yangtze River. Therefore, municipal governments should strengthen the development of cross-regional environmental protection mechanisms, implement holistic resource allocation strategies, and adopt targeted measures to address institutional barriers, thereby fostering coordinated regional development and advancing social harmony and progress.更多还原
