摘要：

利用一个太平洋区域分辨率为12.5 km的ROMS-CoSiNE海洋物理-生态耦合模式1997—2016年的积分结果，对东海黑潮硝酸盐输送的年际变化进行分析。结果显示：东海黑潮的硝酸盐输送存在约3 a与7 a的年际变化周期，且在100～400 m深的次表层与400～800 m深的中层水中变化较为显著。东海黑潮上游海水中，南海水及直接汇入东海黑潮的西太平洋海水对黑潮硝酸盐的年际输送变化具有重要影响。其中，南海水主要影响东海黑潮中层水的硝酸盐输送，而西太平洋海水对东海黑潮次表层水硝酸盐的输送影响较为显著。

Based on the simulation results of a three-dimensional physical-biological coupled model (ROMSCoSiNE) for the Pacific Ocean from year 1997 to 2016, we investigate the interannual variation of nitrate transport by the Kuroshio in the East China Sea. It is found that the nitrate transport shows significant interannual variation with the periods of about 3 and 7 years, and shows significant variation in the Kuroshio subsurface water (100~400 m) and Kuroshio intermediate water (400~800 m). The water from the South China Sea and the west Pacific Ocean play an important role on the interannual variation of the nitrate transport by the Kuroshio in the East China Sea. The South China Sea water influences the nitrate transport in the Kuroshio intermediate water, while the West Pacific Ocean Water affects the nitrate transport in the Kuroshio subsurface water.
