摘要
本文依据热带海洋全球大气研究(TOGA),东太平洋海洋环流研究(EPOCS)、西赤道太平洋海洋环流研究(WEPOCS)、表层热带太平洋观测(SURTROPAC)以及太平洋区域观察)PROPPAC)等计划,对1980～1990年期间在赤道太平洋(141.5°E～85°W,10°N～10°S)所调查的生物化学资料进行了分析和比较。所得结果是:东赤道太平洋正常年份初级生产力为500～800mg/(m^2·d),El Ni(?)o期间约为150mg/(m^2·d);西赤道太平洋正常年份初级生产力为200～250rag/(m^2·d),El Ni(?)o期间约为300mg/(m^2·d)。研究结论是:El Ni(?)o期间东赤道太平洋初级生产力较正常年份显著降低,西赤道太平洋初级生产力较正常年份明显增加,生物响应均较显著。
Based on TOGA(Tropical Oceans and Global Atornsphere), EPOCS (Eastern Pacific Ocean Circulation Study), WEPOCS (Western Equatorial pacific Ocean Circulation Study), SURTROPAC and PROPPAC programs, We analyzed bio-chemical data obtained from the investigation in Equatorial Pacific (141.5° E—85°W, 10°N—10°S) during the period from 1980—1990. The result is that primary production of the Eastern Equatorial Pacific in normal years is 500—800mg/(m^2·d) and about 150mg/(m2·d) during El Nifio, but primary production of the Western Equatorial Pacific in normal years is 200—250mg/(m^2·d) and about 300mg/(m^2·d) during El Nino.
The conclusion is that primary productivity of the Eastern Equatorial Pacific during El Nifio notably decreases than normal, and that of the Western Equatorial Pacific during El Nino obviously increases than norml.
