摘要
对由水域中浮游生物和为其提供营养的生物之间相互作用构成的动力系统进行了研究,得到了该系统在R2+内有唯一渐近稳定的平衡点且无周期轨道,做出了该系统轨线的全局结构,给出了所得结论的生物意义.
A type of dynamic model that describing the biochemical interaction between a phytoplankton and nutrient plankton in a water environment is studied. It has been found that the system has unique asymptotically stable equilibrium in R2^＋ and no any circle orbit. All the results obtained in the paper have been given clear-out biological signification.
