南沙群岛海域夏季沉降颗粒的垂直通量

Vertical Flux of the Settling Particulate Matter in the Waters of the Nansha Islands in Summer

根据１９９９年７月航次在南沙群岛海域现场投放沉积物捕获器所取得的样品及分析结果，计算了南沙群岛海域夏季沉降颗粒的垂直通量、沉降颗粒中有机碳、总磷、有机磷的垂直通量，以及沉降颗粒中有机碳的百分含量。通过与南海其它海区及南沙群岛海域不同季节的沉降颗粒垂直通量作比较，认为南沙群岛海域沉降颗粒的垂直通量具有区域性和季节性的特点。

Based on the samples acquired from the cruise on the Nansha Islands in July 1999 by using the sediment trap and the results of analysis, the Vertical flux of the settling particulate matter is obtained. In addition, the vertical flux of the organic carbon, the total phosphorus and the organic phosphorus in the Settling particles, as well as the percentage of organic carbon in summer are calculated in this paper. By comparing them with the vertical fluxes in different seasons and in different regions of the Nansha Islands, it can be seen that the vertical flux of the settling particulate matter shows a regional and seasonal feature in the waters of Nansha Islands.
