Many subtropical estuaries have the interlinked ecosystem of mangroves, seagrass beds and coral reefs and have kept the delicate balance in nature. This study investigated the spatial and temporal variation of nutrients (NH4-N, NO3-N, PO4-P, TOC and SS), physical parameters (DO) and water currents in discussing the differences in between mangrove river to seagrass beds. TN and NH4-N in the mangrove river mouth were 2~5 times higher than in seagrass bed. PO4-P increased in seagrass beds at the low tide. It means that the ebb tide could have triggered the elution of PO4-P from the bottom in seagrass bed. Water current exhibited the strong seaward flow in the ebb tide and circulating flow in the northeast of the bay. These movements could have affected the material exchanges between the mangrove and adjacent seagrass beds.
