Coastal erosion is an extremely complex natural phenomenon. Because of abnormalities of water and sediment passing from a river basin into the sea, expansion of social economic activities, and urbanization of shore region, coastal erosion has worsened in recent decades under the conditions of global warming and sea-level rise around the world. This poses a serious challenge to ecology and the environment in coastal regions. Thus, coastline erosion in Yintan is assessed and predicted on the basis of historic charts and the Bruun principle in this paper. The research shows that in the last 30 years, human activity has accounted for 98% of coastal erosion in Yintan, dwarfing the impact of the sea-level rise, which only accounted for 2%. Considering the change to the shoreline, we conclude that coastal erosion of Yintan will possibly intensify over a distance over 1 000 m in the next 100 years, which could induce eventual aggradation of the Yintan environment.
