在真实的森林系统中 ,由于外界因素的复杂性 ,森林火灾的自组织临界性要受到影响。森林类型便是影响森林火灾自组织临界性的一个重要因素。本文研究了以密度为控制参数的森林火灾模型以及这个模型在森林密度不同时产生的相变行为 ,发现对过于稀疏或者过于密集的森林类型 ,森林火灾的分布会偏离甚至完全背离幂律关系 ,从而使得自组织临界性不再满足
In real forest systems, the self-organization criticality of forest fires is affected by the complexity of external factors. Forest type is an important factor that affects the self-organized criticality of forest fires. This paper studies the forest fire model with density as the control parameter and the phase change behavior of this model when the forest density is different. It is found that for the too sparse or too dense forest types, the distribution of forest fire deviates or even completely departs from the power- So self-organized criticality is no longer satisfied
