摘要
系统生态学是对生物群落的生存、成长和死亡进行宏观研究。其系统方法论有多种处理问题的方法,特别是框图模型的应用尤其广泛,如在海洋、经济、城市、水体和陆地生态系统均有应用,但仅局限于画画框图讨论而已,并没有指出其应用的实际意义。还有一种系统动力学框图,属臆造模型。
This paper introduces the method of energy flow chart modelling founded by Odum for establishing mathematical model cf ecosystem.Pond is taken as the case example, which is quantified with three effective variants. The energy flows are organisticaily connected by quadratic models. This method provides an effective means for ecosystem research.
