热带西太平洋海洋事件与初级生产力的关系

Primary Productivity in the Western Tropical Pacific and its Relationship with Oceanic Events

本文依据“中、美热带西太平洋联合调查研究”资料,分析了正常年份,El Ni(?)o及La-Nina事件热带西太平洋165°E断面(10°N～6°S)的初级生产力。结果发现,El Ni(?)o及La-Nina期间热带西太平洋165°E断面的海洋初级生产力较正常年份分别增加50%和70%左右。

There are few reports on biological consequences of the Western Tropica Pacific under different oceanic events, due to the lack of systematic data in bio-chemical field. Based on data collected from cruises of USA-PRC joint air-sea interaction studies in the Western Tropical Pacific ocean in 1985～1990, we analyse primary production along 165°E section (10°N～6°S) in the Western Tropical Pacific during normal, El Nino and LaNina events. The resuits show that primary production during El Nino has increased by 50% over normal, and during La Nina event by 70%.
