Abstract
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.
