摘要
１９９３年８月至１９９４年５月四个季度对厦门海域的气溶胶样品总磷含量测定的结果表明，厦门海域大气气溶胶总磷含量平均为６．０３×１０－２μｇ／ｍ３，并呈现干湿季变化特征，夏季雨量丰沛时节含量最低，与降水、风向等气象条件有关．磷的大气沉降通量约９．５×１０－２ｇ／ｍ２．ａ，比北太平洋和南极半岛海域高一个数量级，湿式沉降通量大于干式沉降．与沉积物释放等过程比较，大气沉降不是磷的主要的输入过程。
The aerosol concentration of phosphorus over Xiamen region during August 1993 to May 1994 was measured. The mean concentration was 6.03×10 -2 μg/m 3. It was the lowest in summer, when precipitation was high and southeast monsoon prevailed over Xiamen region. The atmospheric flux was estimated to be 9.5×10 -2 g/m 2.a, which was an order of magnitude higher than that over the North Pacific and the Antarctic Peninsula region. More of the flux was associated with wet deposition than with dry deposition. When compared with other processes such as benthic fluxes, the atmospheric flux seemed not important, however, it did constitute a route of phosphorus input in the study area, and should not be neglected especially in rainy season.
