Abstract A Nutrient-Phytoplankton-Zooplankton-Detritus (NPZD) type of biogeochemical model is developed to investigate the nutrient limitation in the Yangtze River Estuary. By means of a series of numerical experiments, it is found that the phosphate limitation is dominant especially in the coastal region due to the large amounts of riverine nitrogen input. It is also found that the nutrient limitation tends to shift from the P-limitation to the N-limitation toward the offshore region, since the N/P ratio has decreased drastically in this sea region. The difference in the nutrient source may be responsible for shaping such nutrient limitation in the Yangtze River Estuary, since nitrogen mainly comes from the riverine input whereas phosphate mainly comes from either the regeneration process or the intrusion of the branch of the Kuroshio current.
