| 摘 要： | 本文首次描述了本海区中浮游动物生物量及其分布。其平均生物量为41毫克/米~3,仅及东海西部沿海生物量的四分之一,从而表示了一般大洋性的特征。 生物量随水深增加而逐渐下降,其所下降的近似值能以对数关系值表示: logY=α-k~z Y是生物量(湿重),Z是深度, α是常数,k是递减系数。 y=α'e~(-kz) 在东海海槽深海区内,在从表层至100米以内浅水层中,平均生物量为75毫克/米~3,但自500米至2170米水层中,其生物量仅及其上层生物量的1/10或1/20。其变化也可以下列公式来表示: y=58.886e~(-2.074×10~(-3)z) r=-0.7558 r是相关系数。 本文还对浮游动物生物量和渔业水文等之间的关系作了阐述。

| Abstract: | This paper is one of the some zooplankton research reports.It was according to the zooplankton samples which were collected from the deep sea fishing ground of the off continental margin and slope from the East China Sea (including the East China Sea Trough and northern region of Taiwan) by' Dong Fang' research vessel with autoplankton recorder and plankton net during the period from 1980 -1981.In this paper, the zooplankton biomass and its distribution in this area were described at first time. The average... |
