【摘要】 <正> 前言渤海初级生产力的研究,是渤海水产资源增殖计划中的重要研究课题之一。为了估算渤海从初级生产者到渔业捕捞对象各级生物产量和各级营养阶层之间的能量转换关系,首先要研究海洋浮游植物的蕴藏量及其生产能力,即海洋初级生产力。在所有可以用来估算海洋浮游植物蕴藏量的方法中,根据海水中叶绿素含量,来计算海洋浮游植物的蕴藏量的方法,似更多还原

【Abstract】 The phytoplankton phtosynthesis and the rate of assimilation were determined near the mouth of the Haiho River in the Po Hai Bay. The photosynthetic intensity of phytoplankton ranged from 76--170mg C/m~3. day in the euphotic layer, and there is still photosynthesis to be carried out below it. The chlorophyll a concentration ranged from 0.54--2.22mg/m~3, and averaged 1.17mg/m~3. No regularity was found in the vertical distribution of chlorophylla. The rate of assimilation in the euphotic zone ranged from 5.0 to 5.2, with an average value of 5.1, and is less than 3.0 below the euphotic layer.更多还原
