| 摘 要： | 采用分室模型的方法,对农牧结合生态系统的物流情况进行分析,是考察生态系统整体结构特征的重要手段.通过分析物流情况,了解系统中物质循环的特点,从而对系统具有整体性的把握.以黑龙江省双城市双城镇永和村的自然情况为依据,通过提取各分室和考察物质流动情况,建立了系统的线性微分方程组模型,并利用李雅普诺夫线性理论的方法,论证了模...

| Abstract: | This paper analyzed material flow situation in argo-animal husbandry ecosystem by compartment model.This model is an important mean for investigating the whole structural characteristics in Ecosystem.Based on this analysis,characteristics of material cycle and integrity in system were mastered.As an example of natural conditions in Yonghe Village,Shuangcheng Township,Shuangcheng Municipal,Heilongjang Province,the system of linear differential equations was established by extracting each compartment and investigating material flow and stability of this model was proved by Lyapunov linear theory.The results showed that this system could not be interfered by initial value in the state of present,input and output. |
