中文摘要：
基于营养盐、赤潮藻类、碎屑的生物量之间的食物链关系，考虑到由于海洋内微生物分解动植物遗体对营养盐的补充以及物理因素导致的流失，建立了营养盐-赤潮藻类-碎屑的生物量相互作用的耦合生态动力学模型。运用现代非线性动力学理论，对模型解的动力学稳定性进行了分析。结果表明，随着参数的变化，系统稳定性也随之变化，甚至出现HOPF分岔现象。
英文摘要：
Based on the food chain relationship between nutrition, autotrophy and detritus biomass, consid ering the complementarity of the nutrition which is caused by the animalcule decomposition of the propaga- tion reliquiae, as well as its losing caused by physical therapies, we set up a model of zoology dynamics about the reciprocity of nutrition-autotrophy-detritus biomass, and analyze the dynamical stability of the model solution by using modern nonlinear theory. The result indicates that the stability of the model changes even bifurcates along with the change of parameters.
