徂徕山林场雷击森林火险区划模型研究

Study on the Forest Fire Risk Zoning Model for Lightning Strike in Culai Mountain Forest Farm

摘要: 为了研究徂徕山林场的雷击森林火险区划，利用地理信息系统(GIS)将致灾因子、孕灾环境、承灾体暴露度和脆弱性四个方面15个指标进行计算和处理，采用层次分析法(AHP)确定各指标的权重指数，构建雷击森林火险区划模型，分析了雷击森林火险区划在徂徕山林场的分布。结果显示：徂徕山雷击森林火险区划高风险和较高风险区域主要集中在太平顶林区、王庄林区南部、光华寺林区大部等区域；中等风险区域主要集中在茶石峪林区大部、锦罗林区大部、王庄林区北部、太平顶林区西部、光华寺林区北部；较低或低风险区域主要分布在徂徕林区、大寺林区、黄石崖林区、庙子林区、王庄林区东北部局部、锦罗林区北部局部和东南部局部区域。

Abstract: In order to study the lightning forest fire risk zoning of Culai Mountain Forest Farm, a geographic information system (GIS) was used to calculate and process 15 indicators from four aspects: Disaster causing factors, disaster pregnant environment, exposure of disaster bearing bodies, and vulnerability. The Analytic Hierarchy Process (AHP) was used to determine the weight index of each indicator, and a lightning forest fire risk zoning model was constructed. The distribution of lightning forest fire risk zoning in Culai Mountain Forest Farm was analyzed. The results show that the high-risk and high-risk areas of lightning forest fire hazard zoning in Culai Mountain are mainly concentrated in the Taipingding Forest Area, the southern part of Wangzhuang Forest Area, and most of Guanghua Temple Forest Area; The medium risk areas are mainly concentrated in the majority of Chashiyu Forest Region, Jinluo Forest Region, the northern part of Wangzhuang Forest Region, the western part of Taipingding Forest Region, and the northern part of Guanghuasi Forest Region; Low or low-risk areas are mainly distributed in the Sorai Forest Region, Dasi Forest Region, Huangshiya Forest Region, Miaozi Forest Region, parts of the northeast of Wangzhuang Forest Region, parts of the north and southeast of Jinluo Forest Region.
