摘要:
 根据丽江地区1984-2008年林火统计资料,利用GIS空间分析法揭示了丽江地区林火发生的时空分布规律以及影响因素。结果表明,丽江地区林火以1988年为界限,分为1984-1988年的多发期和1989之后的平稳期;丽江地区森林火灾主要发生在春季,3-5月最为严重,占总火灾次数72%;林火空间分布来看,森林火灾高发区域主要分布在海拔1 600~2 800 m,坡度在0°~10°的区域,阳坡发生森林火灾的频率较高;通过道路河流缓冲区分析,在距离河流、道路2 000 m的缓冲区范围内分别有47%和38%的森林火灾发生,这说明林火发生次数与道路以及河流距离密切相关。研究丽江地区森林火灾时空分布特征,有利于把握该地区林火发生规律,为制定科学防火规划和指导森林防火扑救工作提供依据。
Abstract:
 In order to understand the law of forest fires and to provide a scientific basis forest fire prevention and guidance of forest fire fighting,temporal and spatial distributions of forest fires occurring in Lijiang were examined.Based on the data of forest fire statistics in Lijiang area from 1984 to 2008,the temporal and spatial distribution pattern of forest fires and impact factors in Lijiang area were analyzed by GIS spatial methods.The results showed that the times of forest fire in Lijiang area was bounded by 1988 and divided into two phases: high fire occurrence stage before 1988 and stable fire occurrence stage after 1988.Forest fire occurred mainly in spring,the times of forest fires occurred mainly in March to May accounted for 72% of the total.Forest fire were mainly distributed in high-risk area between 1 600 to 2 800 m above sea level,slope from 0°to 10°,and sunny slope was prone to fire.; it was found that 48% and 38% of forest fires on both sides of the highway and the river within the range of 2 000 m through the buffer analysis,which showed that the frequency of forest fires was closely related to the distance between the highway and the river.
