【摘要】Biogeochemical character of dissolved inorganic nitrogen and phosphate at plume front is studied based on the data, which were observed in the Changjiang River Estuary in 1988. The results are as follows: The concentrations of nitrate and phosphate change abruptly at plume front and halocline. The concentrations of NO-2 and NH+4 are very high at 10～25m depth. The vertical circumfluence transports NO-3 and PO3-4 , which are released from organisms at the bottom to phytoplankton. 【总页数】7页(25-31)
