摘 要 ：林火空间分布格局的研究对于林火发生预测以及理解林火在森林景观变化过程中的作用具有重要的意义。运用空间点模式方法对大兴安岭地区1988~2005年间雷击火发生情况进行了统计分析进而确定雷击火空间分布情况，研究结果表明大兴安岭地区雷击火成聚集分布，并存在雷击火热点地区，其核心区地理坐标分别为123°06′E，52°20′N；123°41′E，51°34′N；124°08′E，50°48′N。

Abstract:The study of spatial pattern of forest fire locations is important to predict the fire occurrence as well as to understand the role of fire in landscape processes. A spatial statistical analysis of lightning-caused fires in Daxing′anling between 1988 and 2005, was carried out to investigate the spatial pattern of fires. Fire locations were found to be spatially clustered. The results also showed that there are some “hot-point” areas in Daxing′anling and geographical coordinates of those areas are 123°06′E，52°20′N；123°41′E，51°34′N；124°08′E，50°48′N, respectively.
