[Objective] The aim of this study is to explore the spatial and temporal evolution characteristics, coupling coordination degree and relative development of urban resilience and urban land use efficiency of the Yangtze River Delta urban agglomeration from 2010 to 2020, and to provide reference for promoting the coordinated and sustainable development of the Yangtze River Delta urban agglomeration. [Methods] Taking 26 cities of the Yangtze River Delta urban agglomeration as the research object, based on the entropy method, the coupling coordination degree model and the relative development degree model, the coupling coordination relationship between urban resilience and urban land use efficiency of the Yangtze River Delta urban agglomeration was studied by constructing a comprehensive evaluation index system. [Results](1)During the study period, the urban resilience of urban agglomeration of the Yangtze River Delta showed an overall upward trend, with more than 80% of the cities' resilience levels rising, The urban land use efficiency showed a fluctuating trend. Both of them presented a spatial distribution pattern of ‘high in the east and middle, low in the south and north margins', and the urban toughness changed from relatively scattered distribution to the concentrated distribution, and the urban land use efficiency changed from ‘7' to ‘large' distribution.(2)The degree of coupling between the two was relatively high, mainly at a high level. The overall coordination degree was low, but it showed an upward trend of development and a spatial distribution pattern of ‘high in the east and low in the west, high in the center and low in the periphery'.(3)The urban resilience and urban land use efficiency of nearly 1/2 of the cities had achieved synchronous development. The rest of the cities were mainly advanced(urban resilience was ahead of urban land use efficiency)from 2010 to 2015, and mainly lagged(urban resilience lags behind urban land use efficiency)from 2015 to 2020. [Conclusion] The coupling and coordination level of urban resilience and urban land use efficiency in urban agglomeration of the Yangtze River Delta was low, and the development was unbalanced. The two had not achieved synchronous development. In the future, we should strengthen the regulation and guidance of urban industrial structure and land use layout, promote the regional coordination of urban economy and land use, and coordinate the coordinated development of urban resilience and urban land use.
