| 摘 要： | 1998年2和9月在长江河口淡水端连续观测了DIN(NO3-,NO2-,NH4+),PO43-,流速和流向.结果表明,溶解态无机氮、磷浓度的时空变化较复杂;1998年2月NO3-,NO2-,NH4+和PO43-的月通量分别为168241,974.4,19335和2648t,9月的月通量分别为905678,8317,5797和6281t;1998年NO3-,NO2-,NH4+和PO43-年通量分别为497.1×104,3.911×104,10.22×104和4.155×104t.

| Abstract: | In February and September 1998, concentrations of nutrients (NO - 3, NH + 4, NO - 2 and PO 3- 4), velocity and direction were continuously observed at freshwater end member in the Changjiang Estuary. The results are as follows: Spatio temporal variation of concentrations of NO - 3, NO - 2, NH + 4 and PO 3- 4 are very complicated. In February 1998, the fluxes of NO - 3, NO - 2, NH + 4 and PO 3- 4 are 168 241 , 974 4, 19 335 and 2 648 t , respectively. In September 1998, the fluxes of NO - 3, NO - 2, NH + 4 and PO 3- 4 are 905 678 , 8 317 , 5 797 and 6 281 t , respectively. In 1998, the fluxes of NO - 3, NO - 2, NH + 4 and PO 3- 4 are 4 971 , 39 11, 102 2 and 41 55 kt, respectively. |
