摘要
森林火灾是八大自然灾害之一,具有事发突然、蔓延快、防治难、不确定因素多且损失大的基本特点。以范县地区为例,采集森林火灾可燃调查数据,数据包括地表覆盖物、腐殖质厚度、林木密度、蓄积量、可燃物实验检测等,将调查单元(样方)的危险性评估各项指标数据化和指标化,带入危险性指数计算公式,通过ArcGIS软件导出危险性等级图,并评估单元的承灾体暴露度等级和承受体脆弱性,带入风险指数计算公式进行计算,通过ArcGIS软件导出风险性等级图,分析得出范县总体森林火灾发生可能性和危险性为中等水平,针对此情况采取加强森林防火队伍建设和物资储备措施,做到监管有效、防患未然,为我国平原地区森林防火提供理论依据。
Forest fire is one of the eight natural disasters,which has the basic characteristics of sudden occurrence,rapid spread,difficult prevention and control,many uncertain factors and great loss.Taking Fan County as an example,forest fire combustible investigation data were collected,including ground cover,humus thickness,forest density,stock volume,experimental detection of combustible materials,etc.The risk assessment indicators of the investigation unit(sample plot)were datfied and indexed,and the risk index calculation formula was introduced.The risk grade map was derived by ArcGIS software.The exposure level of the disaster bearing body and the vulnerability of the disaster bearing body of the unit were evaluated,and the risk index calculation formula was introduced for calculation.The risk level diagram was derived by ArcGIS software,and the analysis concluded that the overall possibility and risk of forest fires in Fan County were at a medium level.In view of this situation,measures were taken to strengthen the construction of forest fire prevention teams and material reserves,so as to achieve effective supervision and prevent disasters.It provides theoretical basis for forest fire prevention in plain area of China.
