The issue of urban resilience plays great significance and value for the sustainable development of cities, which has attracted increasing attention from scholars and governments, especially in the western region of China. Based on the Production-Living-Ecological (PLE) system, this study attempts to describe urban resilience by the combination system that contains with P,L,E subsystem. The integrated approach including FAHP-EM,GRA-TOPSIS, CCDM, and ODM is proposed to reveal the urban resilience level and seek out the key constraints’ indicators. Then, an empirical analysis of panel data of 18 cities in Sichuan Province from 2011 to 2021 was conducted to analyze the development process. The valuation results suggested that:(1)for urban resilience level, most cities at the moderate imbalance level and basically maintained at this level, only Chengdu is reaching the basic coordination level since in 2013.(2)The insufficient development of P,L,E subsystem is the reason for the moderate imbalance development, especially the key limiting factor is the P subsystem’s low development level.(3)the most prominent obstacle indicators are x1(per capita local financial expenditure on science and technology), x2(per capita of R&D spending), x8(total export-import per capita), x14(number of people with basic medical insurance), x22(length of urban drainage pipeline), x23(number of public toilets per person) and the contribution values reach 7.56%,7.49%,11.02%, 9.14%,12.53%, 12.60% respectively. The detailed reference suggestions and effective measures put forwarded for policy makers and planners to promote urban resilience in Western China.

城市韧性（urban resilience）问题对于城市可持续发展具有重要意义与价值，已日益受到学界与政府的广泛关注，在中国西部地区尤为突出。本研究基于生产-生活-生态（Production-Living-Ecological, PLE）系统，尝试通过包含生产、生活、生态子系统的复合系统对城市韧性进行刻画。本研究提出了融合FAHP-EM、GRA-TOPSIS、CCDM与ODM的集成研究方法，用以研判城市韧性水平并识别关键约束性指标。随后，本研究以四川省18座城市2011至2021年的面板数据为样本开展实证分析，探析其城市韧性的发展历程。评估结果显示：(1) 在城市韧性水平层面，多数城市处于中度失调状态且基本维持该水平，仅成都市自2013年起达到基本协调状态；(2) 生产、生活、生态子系统发展不充分是导致中度失调的核心原因，其中生产子系统发展水平偏低为关键制约因素；(3) 最突出的障碍指标依次为x1（人均地方财政科技支出）、x2（人均研发经费投入）、x8（人均进出口总额）、x14（基本医疗保险参保人数）、x22（城市排水管道长度）、x23（人均公共厕所数量），其贡献占比分别为7.56%、7.49%、11.02%、9.14%、12.53%、12.60%。本研究为政策制定者与规划者提出了具体参考建议与有效举措，以助力中国西部地区城市韧性的提升。
