“…The main cause of eutrophication is an abnormal increase in the primary productivity of waters [ 2 ]. In recent decades, the problem of eutrophication in offshore areas has been one of the severe marine environmental problems that beset coastal countries around the world [ 3 ]. Human activities have intensified the transport of nutrient elements such as nitrogen and phosphorus to oceans, causing changes in the composition and degradation of functions of the ecosystem, and a series of problems such as ecological risk disasters that severely threaten the health of the ecological environment of coastal waters [ 4 , 5 , 6 , 7 , 8 , 9 ].…”

The eutrophication of coastal water has been a critical environmental problem in China’s offshore areas. How to effectively assess the status of coastal waters is key for pollution treatment and environmental protection. In recent years, eutrophication-symptom-based and multi-indicator methods, termed “phase II” methods, have been gradually adopted to assess the eutrophication status in some coastal waters in China and have achieved success. The cumulative quantile is typically selected to determine the characteristic value of an indicator in “phase II” methods. The influence of small-scale damaged water bodies on eutrophication assessment may be exaggerated, which often leads to the overassessment of the eutrophication status. In this study, the area ratio method was integrated into the assessment of the estuarine trophic status (ASSETS) method in order to assess the eutrophication status of Xiamen Bay in 2016. The results indicated that, in 2016, the eutrophication status of Xiamen Bay coastal waters was moderate and exhibited spatiotemporal variation. The area ratio method can effectively reduce the effect of small-scale coastal waters with extremely high eutrophication on the overassessment of eutrophication at the broader scale, allowing the eutrophication status to be better reflected, even with limited observation data. The centralized distribution of pollution sources and poor hydrodynamic conditions are the main reasons for the aforementioned phenomenon. Controlling the pollution discharge from the Jiulong River in flood seasons is key to reducing eutrophication in Xiamen coastal waters.
