Abstract

Under the challenge of global environmental change and rapid development, tremendous risks brought about by natural disasters and human activities have increased environmental pressures for sustainable development. How to improve coastal resilience in the process of urban development has become an important topic in academia. In this study, a variable fuzzy recognition model was used to measure the level of coastal resilience in 17 cities in the Bohai Rim region, and then the kernel density, thiel index, and random forest model were used to explore the spatiotemporal characteristics and influencing factors of coastal resilience. The results show that (1) The overall resilience level of the Bohai Rim region is increasing over time, but at a relatively slow rate. (2) Coastal resilience has significant spatial unevenness, with high-level cities dominated by Tianjin, Qingdao, Yantai, etc. and low-level cities dominated by Cangzhou, Panjin, Yingkou, Binzhou, etc. (3) The influence of economic development, infrastructure, innovation ability, technology investment, and government regulation on coastal resilience decreases in order. Based on the research findings, the study can not only make suggestions for the actual regulation strategy but also provide empirical and theoretical experience for other coastal countries.
