摘要:

重点综述了中国森林火灾系统的宏观规律之一--"自组织临界性"的研究,包括:(1)对中国1950年至1989年的真实森林火灾数据进行了分析,并发现了自组织临界性;(2)综合真实森林火灾系统所受到的外界因素(包括人为、环境、树种等),对经典森林火灾模型进行了修正,并构建了新模型;(3)模拟了森林火灾模型的有限尺度效应,分析了它的实际意义.

关键词: 自组织临界性, 元胞自动机, 森林火灾模型, 有限尺度效应

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
