Study On The Relationship Between Forest Stand Structure And Fuel Characteristics Region Of Beijing

In this paper, the author has summed up the home and abroad forest fuel studying current situation and the developing trend. The main content of forest fuel are such as: the physicochemical property of the fuel, the distribution and disposition of the fuel, the division of the fuel types and the research and development of the fuel models. The author studied the forest fuel from aspect such as fuel characteristics, fuel model, inflammable grade partition around Beijing .The fuel models of the surface fuel of all types were established by introducing the standing forest factors such as forest age, canopy density, mean height and diameter breast height. The fitting effect of the models is satisfactory, so it is feasible that the surface fuel are estimated by using the standing forest factors.126 primary class of forest farm is an object of study with the Ming Tombs , take that plant species of trees, standing forest age , canopy degree , slope, inflammable fuel load, grass height and cover, bush height and cover degree as fundamental factor, is tied in the fuel characteristic, load characteristic and the fuel distribution characteristic, carry out an ordering on fundamental factor inflammable , assign value and dividing the certain grade, Reach the not burning , difficult to burn , to combustible , to inflammable , to burn by force five inflammable grade, what every grade takes up area has brought forward the measure managing and managing respectively for 1.41% , 7.78% , 31.32% , 34.81% , 24.67% , specifically for such fuel characteristic.
