Global climate change brings stronger climate risks,and the assessment of urban resilience can identify weak links in urban development and propose improvements.This paper analyzes the resilience changes of cities in the face of multiple disaster risks from the perspective of climate risk,constructs a resilience assessment system under climate risk from the four dimensions of vulnerability of disaster-bearing bodies,sensitivity of hazard-inducing environment,risk of disaster factors and disaster prevention and mitigation capacity,provides a theoretical basis,and evaluates the indicators and comprehensive resilience of the central area of the Yangtze River Delta from 2010 to 2021 by constructing a genetic algorithm model and a coupled incentive evaluation model based on projection tracing for nonlinear evaluation.The main influencing factors affecting the change in urban resilience are analyzed,and the temporal and spatial evolution characteristics of their distribution are identified.Finally,according to the results,suggestions on resilience improvement are put forward,which provides references for the research and construction of resilience in the central area of the Yangtze River Delta.
