Abstract: With the continuous change of the marine ecological environment, the uncertainty disturbance faced by the coastal zone is also increasing. The resilience of the coastal zone directly affects the sustainable development of the coastal zone ecology. Based on the theory of resilience, this paper clarifies the connotation of coastal zone ecological resilience, builds an evaluation index system based on the fuzzy matter-element analysis method, uses the data of provinces and cities around the Yellow Sea and Bohai Sea from 2011 to 2019, analyzes the space-time characteristics and barriers of coastal zone ecological resilience through the model, and puts forward suggestions to improve the coastal zone ecological resilience. The results show that the coastal zone of Shandong and Hebei has a high level of ecological resilience and a good trend of sustainable development.The ecological resilience level of Tianjin is low, but the trend is getting better. The ecological resilience of Liaoning and Jiangsu has declined in recent years.The ecological resilience of the coastal zone around the Bohai Sea and the North Yellow Sea is gradually rising, while that of the South Yellow Sea is declining. The status of marine habitat and the intensity of ecological response are the main obstacles to the ecological resilience of the coastal zone around the Yellow Sea and Bohai Sea.
