Urban rivers are vital for urbanization and regional economic development, which can provide water for living, industrial and agricultural needs of urban residents, and regulate the hydrological environment in the urban. The exploration of urban rivers health based on resilience theory can provide important reference for urban rivers restoration and resilience urban construction. To this purpose, this study explores the health status of Jialu River during 2011–2020 from the perspective of resilience. First, a comprehensive indicator system based on the resilience theory was established for the health analysis of urban rivers. Second, an urban rivers resilience index (URRI) was developed utilizing the improved FCM-EWM-MABAC method to accurately illuminate the health states of urban rivers. Final, the health state of Jialu River from 2011 to 2022 was diagnosed using the comprehensive indicator system and URRI. Our results suggested that the Jialu River’s health state showed a rapid improvement trend from ordinary state in 2011 to good state in 2020. The health status of resistance, recovery and adaptability subsystems displayed different degrees of improvement during the study period, and the growth trend of adaptability subsystem was the most obvious. Over the past decade, the resilience state of Jialu River had improved by implementing a series of governance measures, but there is still room for improvement. This study can provide significant references for future work on the water resource conservation and sustainable development in rapidly economic developing regions. |
