To improve the ecological resilience of Chongming Island, we explore the interrelationship between the government's construction orientations and its ecological resilience. Further evaluation reference for near-continental urbanized islands are provided. In this paper, the ecological resilience evaluation system, based on the landscape pattern-process-PSR (Pressure-State-Response) model, is constructed to evaluate the ecological resilience of Chongming Island by integrating landscape background quality, pressure factors, and anthropogenic response. The results show that Chongming's resilience score is divided into two stages. The first stage is the resilience weakening period from 1990 to 1999, except for a little increase from 0.3699 to 0.3979 between1990 and 1991, the left resilience score between 1991 to 1999 kept declining to the lowest0.2382 in 1999.The second stage is the resilience-building phase between 2000 and 2020, during which Chongming's resilience increased rapidly, with stagnation between 2011 and 2015, and high growth resumed after 2015. The findings suggest that the changes in ecological resilience in Chongming are closely related to government’s planning orientations.
