摘要:

根据北京市1986—2006年森林火灾统计数据,运用统计分析方法和地理信息系统空间分析方法,对北京市森林火灾的时空分布规律进行研究。结果表明:1986—2006年,北京市森林火灾年际间波动较大,但总的趋势是在逐渐减少; 北京市森林火灾多集中于春季; 一天中的森林火灾统计曲线大致呈马鞍型,自11:00和14:00分别向两端降低。北京市森林火灾空间分布特征明显:着火地点大多集中分布在平原与周围山地相接的边缘地带; 各区县森林火灾分布不均; 森林火灾随距离公路变远而呈减少趋势,局部区域范围火点数量呈不规则变化特征; 除林地外,林地周围的草地、旱地、农村居民用地和其他用地的火源,都可能蔓延而形成森林火灾。建议根据森林火灾的发生规律与特点,对首都市民开展森林防火教育,健全森林防火组织机构,加强森林防火基础设施建设,提高首都森林防火的整体能力。

Abstract:

Based on data of forest fire statistics in Beijing from 1986 to 2006, a temporal and spatial distribution pattern of the forest fires was analyzed by using the statistic analysis and GIS spatial analysis methods. Results indicated that annual forest fires varied significantly from 1986 to 2006, but the general trend was gradually declining. Beijing forest fires were mainly occurred in the spring. The daily pattern of the forest fires roughly exhibited a saddle-shape, and the two peaks respectively were at 11:00 and 14:00. The spatial distribution characteristics of the forest fires were obvious: Most forest fire sites lay in the edge zone between the plain and the surrounding mountains. There was an irregular distribution of the forest fires in each district and county. The farther from the road, the less the forest fires occurred. However, in some small parts, there was no regular in the number of forest fires. In addition to woodland, grassland, arid land, rural residents and other areas surrounding woodland were also places for fire ignitions to form forest fires. It is suggested that forest fire prevention education should be developed; forest fire prevention organizations should be further improved, the infrastructure and related work of fire prevention should be strengthened to improve the overall forest fire prevention capacity of our capital according to the pattern and the characteristics of the forest fires.
