“…The analysis showed that there were significant differences in perceptions of different stakeholders regarding the effectiveness of the current tourism development on the island due to the impact of the epidemic, such as the effectiveness of maintaining local boatmooring space, tourist resting and parking facilities, landscape and historical sites, the littering behavior of tourists, heavy oil discharge pollution, waste garbage and oil pollution on the harbor surface, destruction of marine habitats, heavy oil discharge pollution, tourism waste, and threats from foreign species.
