Every part of phosphorus emitted by man-made can eventually enter the water body to produce a cumulative effect.Therefore, strengthening the management of watershed phosphorus is crucial to protecting the offshore ecological environment and can effectively reduce the occurrence of harmful algae blooms and hypoxic areas.This not only maintains ecosystem service functions (such as fishery, tourism), but also requires the sustainable development of coastal socio-economics. In the context of climate change, nutrient factors need to be included in the forecast and planning of marine carbon sinks and fishery management.Scientific research should continue to promote the monitoring and mechanism research of the ocean's phosphorus cycle, such as developing new sensors and satellite remote sensing inversion of seawater phosphorus content, strengthening the monitoring of indicators such as marine alkaline phosphatase, and timely grasping changes in global nutritional status; at the same time, making full use of genomics and culture experiments to clarify the phosphorus metabolism mechanism of key species, and provide parameters for model construction.
