Study on Forest Fuel Classification and Fire Danger Rating System of Maoershan National Park;

帽儿山国家森林公园可燃物类型划分及火险等级预报系统的研究

Taken forest farm of Tahe forest bureau as study unit,according to integrated caloric assessment value of each farm,fire danger rating of forest fuel type for each forest farm was divided by the potential fire danger rating value.

以塔河林业局的林场为单位,根据森林资源特性的评定值来综合评定各林场的火险,而后依据各林场潜在的火险值(D)的大小,来划分各林场的森林可燃物的火险等级的高低。

And the forecast system of fire danger grade of West Mountain Forest Farm has also been realized by means of VB and MapX design.

在调查和分析北京市西山试验林场的气象、森林资源、人为活动和林火档案等数据基础上,运用综合指标打分法建立了1个基于气象因子、可燃物因子、地形因子、人为因子的林场火险等级预报模型。

According to the historical data concering forest fire occurrence , the maps of fire occurrence, distribution of fire sources, fire danger grades and the disposition of fireproofing facility and manpower were drawn.

根据庐山林火发生历史资料 ,研制了林火发生图、火源分布图、火险等级图和防火设备、力量配置图 ,提出了加强庐山火源管理措
