摘    要:摘要:运用分形理论,对1987-2010年福建省森林火灾受灾面积的时间序列进行分析,重构其嵌入相空间序列,计算关联维数和饱和嵌入维数,得出模拟相应动力系统所需独立变量的控制参数为9个.该方法能够客观、合理地反映森林火灾系统的分形特征,能为建立森林火灾受灾面积时间序列的预报模型提供基础信息.

关 键 词:森林火灾  时间序列  分形  关联函数  福建省

Abstract:Based on the fractal theory, the time-series of damaged area of forest fire disaster in Fujian Province from 1987 to 2010 were analyzed, the time-series of imbedding space were rebuilt, the correlative dimension and saturation embedding dimension were calculated. It was determined that the independent control parameters number to simulate correspond dynamics system were nine. This method could reflect fraetal characteristics of damaged area objectively and reasonably. The obtained conclusions will provide basic informations for establishing the forecast model of damaged area of forest fire disaster.
Keywords:forest fire  time-series  fractal  correlative function  Fujian Province
