摘　　要：以北京市西山试验林场分场魏家村林场为研究区域,系统地研究了火发生历史、可燃物分布、主风向、坡度、山脊、防火公路、居民区分布等,确定了网络适宜的最小控制面积,通过面向对象的分类方法对林中空地和防火公路进行分类,筛选适宜建山脊防火林带的坡度和山脊线,进而确定防火林带的空间格局。共规划三类防火林带:山脊防火林带、防火公路防火林带和林缘防火林带,整个防火林带网络将整个区域分割成不等大小的独立单元,平均面积为41.24 hm2,防火公路总长36 816 m,防火网络总面积占研究区域面积的7.35%。The authors planned the shaded fuelbreak in Weijiacun Forest Farm in Xishen of Beijing,studied the fire regime of this region,fuel distribution,main wind direction,slope,ridge,roads,and residences,and studied the influence of these factors on spatial pattern of shaded fuelbreak.The authors analyzed the suitable area of fuelbreak network controlled,and extracted the roads and open space in forest with the method of object-oriented classification.Three types of fuelbreak were planned： ridge fuelbreak,roads fuelbreak,and forest edge fuelbreak.The fuelbreak network divided the forest into different independent cells,and the average area of the cells was 41.24 hm2.The length of the network was 36 816 m,and the area of the network accounts for 7.35% of the region.
