松花江哨口至松花江村段浮游植物光合作用产氧模型研究

A PRELIMINARY STUDY ON THE PLANKTON OXYGEN PRODUCING PATTERN BY PHOTOSYNTHESIS IN THE SONGHUA RIVER

为研究松花江哨口至松花江村江段的水环境容量，本文从浮游植物光合作用机理出发，利用连续３年多项指标实测资料，采用外包线法，初步确定一种浮游植物光合作用产氧率计算关系式。将这种方法应用于研究江段效果较好，经相关性检验，ｒ＝０．９０，ｒ＞ｒ０．０１，相关性极显著。该计算式能否用于哨口至松花江村以外的江段，尚需进一步验证。

According to the principle of photosynthesis of plankton,our paper presents the formula of oxygen producing pattern,The section of shaokou to Songhuajiang town was chosen for monitoring points in the Songhua River.Various indexes of plankton on the section were studied for three years from 1983 to 1985.We preliminarily built plankton oxygen producing pattern by photosynthesis,and tested relativity of the pattern.The relative coefficient is 0.90,and r>r0.01.The relativity is the most remarkable.It will remain to be confirmed that the formula can be used in other sections of the Songhua River.
