Abstract:

The macro-characteristics, the self-organized criticality (SOC) in particular, is useful at fire protection. The paper reviews the study on SOC of authors, including: (1) SOC analysis of forest fire data between the period 1950~1989 in China.(2)construction of a generalized forest-fire model combining environmental conditions, tree species and efforts of human beings.(3)the finite-size effects of forest-fire model. The practical implications of these studies are also analyzed.

Key words: self-organized criticaligy, cellular automata, forest-fire model, finite-size effects
