A minimum stoichiometric carbon and nitrogen model of an entire ecosystem based on Dynamic Energy Budget (DEB) theory is presented. The ecosystem contains nutrients, producers, consumers, decomposers and detritus. All three living groups consist of somatic structure and either one (consumers and decomposers) or two (producers) reserve compartments, hence the living matter is described by seven state variables. Four types of detritus are distinguished. As the system is closed for matter, the dynamics of the nutrients carbon dioxide and ammonium follow automatically from the dynamics of the other 11 state variables. All DEB organisms in the model are V1-morphs, which means that surface area of each organism is proportional to volume. The resulting ontogenetic symmetry implies that complicated modelling of size structure is not required. The DEB V1-morph model is explained in detail, and the same holds for the idea of synthesizing units, which plays a key role in DEB modelling. First results of system dynamics are presented.
提出了一个基于动态能量平衡（DEB）理论的整个生态系统的最小化学计量碳氮模型。该生态系统包含营养物质、生产者、消费者、分解者和碎屑。所有三个生物群体都由体细胞结构和一个（消费者和分解者）或两个（生产者）储备隔室组成，因此生物量由七个状态变量描述。区分了四种碎屑类型。由于系统物质封闭，二氧化碳和铵等营养物质的动态变化自动遵循其他11个状态变量的动态变化。模型中的所有DEB生物都是V1形态，这意味着每个生物体的表面积与体积成正比。由此产生的个体发育对称性意味着不需要对大小结构进行复杂建模。详细解释了DEB V1形态模型，合成单元的概念在DEB建模中起关键作用，情况也是如此。给出了系统动力学的初步结果。
