| City is a complex multi-functional comprehensive system.In recent years,scholars at home and abroad have followed the theory of sustainable development and focused on the study of urban resilience on the basis of urban development.Urban resilience refers to the city is subjected to the impact of external natural factors or human factors interference or even destruction.The ability of urban systems to resist interference and recover quickly.In the process of urban development,cities will face all kinds of problems,such as the disharmony between urban resources and urban development,the vulnerability of cities to natural disasters due to their geographical location,and the disease of large cities.And the different development modes of cities lead to different growth rates of population,different directions of industrial structure optimization and adjustment,different limits of environmental carrying capacity and other single city development problems.The research of urban resilience has a wide range of perspectives and plays a positive role in the future development of cities.Therefore,it is of great significance for urban research to analyze urban resilience,study the factors affecting urban resilience and urban development,and explore the model suitable for urban development and urban resilience improvement.Based on the data of Sichuan province from 2010 to 2020,this paper conducts a comprehensive study on urban resilience from four aspects: urban infrastructure resilience,urban economic resilience,urban ecological resilience and urban spatial form resilience.Based on this,the prediction value of urban resilience of Sichuan province from 2022 to 2030 is made,and a horizontal comparison is made based on the data of cities in Sichuan province to explore the path suitable for the development of Chengdu.The research content and main conclusions are as follows:（1）Based on ecological carrying capacity theory,sustainable development theory,urban vulnerability theory,life cycle theory and adaptive cycle theory,and based on the statistical yearbook data of Sichuan province from 2010 to 2020,a comprehensive evaluation index system of urban resilience in Sichuan province was constructed.（2）The resilience index of various dimensions of cities in Sichuan province was analyzed.In terms of the annual value,deyang city and Mianyang city in Sichuan province,which suffered from natural disasters such as Wenchuan earthquake in 2010 and suffered serious damage,showed low economic resilience value,and the growth rate of economic resilience was faster at the node of 2015.In the overall four dimensions,only Chengdu ranked first.On the whole,urban resilience in Sichuan province showed a gradual upward trend from 2010 to 2015,but some cities did not improve significantly.From 2015 to 2020,urban resilience showed a significant upward trend.From the perspective of space,the spatial distribution of urban resilience is uneven,showing strong central agglomeration,and decreasing urban agglomeration outwards,and decreasing urban resilience value.（3）From the sichuan province city toughness influence factors were analyzed,and through the lateral comparison between different cities and different years,urban infrastructure construction of urban economic development is one of the biggest impact on the city toughness two impact factors,the second is the construction of urban space form,and the influence of the city’s ecological resilience building is the smallest.From the perspective of overall influencing factors,slow urban economic development,imperfect infrastructure construction,less urban built-up area,poor environmental protection and resource management will hinder the improvement of urban resilience to varying degrees.（4）In the dynamic prediction analysis from 2022 to 2030,the overall urban resilience of Sichuan province tends to be stable,and the proportion of cities with higher resilience is relatively low.Cities with high resilience are included in the Chengdu Plain urban agglomeration.（5）According to the future planning and development of Sichuan and the prediction of resilience,make corresponding resilience improvement strategies.In the aspect of urban infrastructure construction,the management mechanism of urban basic transportation system,pipe network system and urban emergency rescue should be established and improved.In the aspect of urban ecological resilience construction,we should improve the urban geological disaster prevention network driven by resource exploitation,and improve the urban ecological environment management institutions.In the economic toughness construction,optimize the industrial structure,actively cultivate new enterprises and new formats of chengdu,further develop tourism. |
