我们研究了Drossel和Schwabl最近在一篇论文中介绍的森林火灾模型，通过模拟具有高统计量和非常接近临界点。这样，我们就可以纠正该文件中的一些说法。特别是，我们发现，临界指数是不是“经典”的Drossel和Schwabl提出的。尽管标度律与异常指数，系统的典型状态是不是“临界”的意义上是边缘稳定的本地。
We study a forest-fire model recently introduced in a paper by Drossel and Schwabl, by means of simulations with high statistics and very close to the critical point. In this way we can correct some statements made in that paper. In particular, we find that the critical exponents are not the 'classical' ones proposed by Drossel and Schwabl. In spite of scaling laws with anomalous exponents, the typical states of the system are not 'critical' in the sense of being marginally stable locally.
