摘　　要：目前描述好氧生物堆肥过程中有机质降解的模型可归纳为3类:一级反应模型、Monod模型和经验模型。Monod模型的理论基础较好,但模型参数多且其求解过程复杂;一级反应模型的理论基础略次于Monod模型,但其预测效果优于Monod模型;经验模型不能揭示有机质反应过程的机理,预测效果和普适性较差,但模型比较简单。综合来看,在目前对生物堆肥过程中有机质降解的研究和了解很有限的前提下,在一级反应模型的基础上进一步改进模型和提高模拟精度,是生物堆肥过程中有机质降解模拟的主要发展方向。For organic matter （OM） biodegradation in aerobic composting process, there are three types of models： first-order reaction model, Monod model and empirical model. Compared to the first-or- der reaction model and empirical model, the Monod model can preferably describe the theory of the biodegradation process of OM. However, more parameters make Monod model solve harder than the other two types of models. The first-order reaction model has weaker theory but better prediction effect than Monod model. Even though the empirical model is the simplest, it can not explain the biodegradation process of organic matter, and the prediction fitness and extension are poor. So, considering the research on the composting biodegradation process is not enough, the future work is suggested to focus on improving the first-order reaction model and the simulation precision.
