| 摘 要： | 利用森林植物种类组成及林地面积资料,采用面积权重及统计聚类分析的方法,将中国省域森林火险划分为五级,即:轻度危险、中度危险、高度危险、重度危险和极度危险,县域森林火险划分为四级,即:轻度危险、中度危险、高度危险和重度危险.结果表明:黑龙江、内蒙古、陕西3省区为我国森林火灾重点防火区,其中黑龙江最重;我国12.2%的县域处在重度危险等级中,61.5%的县域处在中、高度危险等级中.

| Abstract: | The partition of the risk of forest fire in provinces, municipalities, cities and counties of China is studied. According to the data of forest area and the information of the components of forest tree , five grades are adopted for provinces partition:low risk, middle risk, high risk, upper risk and extremely risk, and four grades are adopted for counties partition:low risk, middle risk, high risk and upper risk. Using the method of area weight and clustering analysis, main findings are as follows: three provinces and municipalities such as Heilongjiang, Inner Mongolia and Shannxi are key fireproofing provinces in China; there are 12.2% of the counties in the upper risk grade and 61.5% in the mid-high risk grade. |
