Resilience assessment of the Yangtze River Delta urban agglomeration based on Multi-barrel Model
This paper established an evaluation model of urban resilience level by comprehen-sively using the multi-barrel model,the entropy method,the catastrophe theory and the barrel theory.And starting from the three characteristics of the resilience system's resistance,absorp-tive capacity,recovery and adaptability,a three-stage evaluation index system of urban resilience level,including three first-level and 12 second-level indicators,is constructed.Taking China's Yangtze River Delta urban agglomeration as an example,this paper calculated the resilience of the Yangtze River Delta urban agglomeration and 26 cities in the urban agglomeration from 2010 to 2019.Then,applying the barrel theory,26 cities were analyzed over time according to the type of"Municipality directly under the Central Government-Provincial capital city-Prefecture level city".The results show that from 2010 to 2019,the overall resilience level of the Yangtze River Delta urban agglomeration has a good development trend and reached moderate resil-ience.However,Xuancheng,Tongling and Chizhou are the shortcomings of the resilient devel-opment of the Yangtze River Delta urban agglomeration,which needs to be focused on in the fu-ture.In addition,the resilience level of cities in the Yangtze River Delta urban agglomeration presents an olive-shaped structure of"large in the middle and small at both ends";Among them,Shanghai has always been highly resilient,ranking first among 26 cities;Its three-dimensional capability heterogeneity evolution of resilience is consistent with the principle of barrel theory.Among the provincial capital cities,Hangzhou's resilience short board has been improved much faster than Nanjing and Hefei.Hence,its resilience level improvement effect is more signifi-cant.Moreover,the resilience level of the 22 prefecture-level cities has a two-level differentia-tion pattern of"High in the east-Low in the west".
