池塘浮游植物生态种组的研究

THE STUDY ON ECOLOGICAL SPECIES GROUPS OF PHYTOPLANKTON IN THE POND

本文在对池塘浮游植物生物量研究的基础上发现:池塘浮游植物根据它们对环境的适应方式可划分为四个生态种组,生态种组A是一个环境适应能力强,但竞争力弱的类群;生态种组B的动态变化过程与水体中无机氮的含量密切相关;而生态种组C的动态变化过程受水体无机氮含量影响较小;生态种组D是与生态种组A和B相抗衡的一个类群。

In this paper, on the basis of seasonal changes of phytoplankton biomass in the pond, the phytoplankton can be divided into four ecological species groups, according to the adaptive mode of phytplankton to the environment. Ecological species group A has a stronger adaptive ability to the environment, but the competitive ability of that is weaker, The dynamics of ecological species group B is very relative to the content of inorganic nitrogen in the water, and the content of inorganic nitrogen in the water has a little effect on the dynamics of ecological species group C. Ecological species group D always competes with group A and B.
