Marine plastic debris pollution is a global environmental issue. Due to the persistence and universality of plastics debris pollution in marine environment, its impact on marine biodiversity has attracted a worldwide attention. In this paper, Relative Risk Model was applied to assess the potential ecological risk of marine plastic debris on Indo-Pacific humpback dolphin (Sousa chinensis) in Xiamen Bay. Four different sizes of plastic debris were defined as risk sources and S.chinensiswas defined as risk receptors.Spatial analysis tools in GIS were used to evaluate and quantify the ingestion risk of plastic debris on S.chinensisandits spatiotemporal distribution. The debris size and impacted area withhigh-risk types, as well as the drivers for high-risk were also identified. The results showed that different sizes of marine plastic debrishad a different potentialecological risk to S.chinensis, with small and medium plastic debris had a higher risk than that of large debris. The spatial and seasonal differences were significantin the ecological risk of debris on S.chinensis. Higher risks were found in summer and winter,this is mainly because of high debris loading due to intensive typhoon and tourism activities in summer, and astronger activity of S.chinensis in Winter. The highest riskswere found in the waters of Dadeng Island and Jiuyu Island in summer, while in winter the highest risks were found in the waters of south of Xiamen Western Seaand Jiuyu in Jiulong River Estuary in winter. The results can provide information to support the decision-making for the managementof S.chinensis conservation in Xiamen Bay.
