摘要: 利用北京市房山区1988—2006年的林火数据,结合背景地理数据,使用数盒子法计算了相关地理要素的分维数,研究了林火发生次数和地理要素分维数之间的关联关系。结果表明,林火次数与居民点和水系分维数变化趋势相反,而与道路和林区的分维数变化趋势相同。

关键词: 林火, 分形理论, 分维数

Abstract: Based on the forest fire data collected during 1988 to 2006 and related geographical data in Fangshan District of Beijing,this paper computed fractal dimensions of forest area,road,river and village by the method of box-counting and then discussed the relationship between these fractal dimensions and occurrence times of forest fires.The results indicated that the bigger the fractal dimensions of forest area and road were or the smaller the fractal dimensions of village and river were,the more forest fires happened.

Key words: forest fire, fractal theory, fractal dimension
