GIS-Based Forest Fire Risk Zone Of Aershan Xingan Forestry

This paper choiced Inner Mongolia Aershan Xing an forestry for the study, Combine the 2009 inventory data Aershan region、Aershan region administrative map、Aershan topographic forest map area collected from the local forestry administrations. Use the principles and methods of geographic information systems on Aershan Xing an forestry forest fire danger factor studied. Use overlay analysis and buffer analysis method for each fire risk factor analysis, and set up the establishment of thematic maps. Applying AHP at a reasonable reference system for each fire factor assignment. Finally, the use of geographic information system implemented method of forest fire risk zone Xing an forestry. Local forestry administrations decision support in fire prevention work. The main conclusions:1.Xing an forestry fire danger rating intermediate and above accounted for70% ofthe total area of forestry,21,000 hectares. Therefore It is important for the local forestry department to get the forest fire Prevention well.2.Within 1000 metres is the high fire danger division near the highway, during the tourist season it is important for the local forestry administrations to check the vehicles,and we must be pay attention to fire tools.The government and the local forestry administrations should be make the propaganda work well.3.In the central and southeast areas of Xing an forestry distribute the high fire danger division,in the central north and southwest areas of Xing an forestry distribute intermediate fire danger division the local forestry administrations should be refer to the figure.In this way can make the resources reasonable allocation and increasing investment can reduce the dangers of forest fires.
