摘　　要：为了解与分析森林雷击火灾的动态行为,进行森林雷击火灾风险评估分析,以减少或避免因雷电而引发的森林火灾、人员伤亡和设备毁坏所造成的损失,本文以2007—2018年山东省闪电定位系统监测数据资料、闪电监测资料、天气和气候观测资料、林场高程数据、地理信息数据、现场勘查资料和客户所提供的相关资料等为依据,采用统计分析法、相关分析、叠置分析和缓冲区分析等多种分析方法,对徂徕山地区雷电活动时空分布特征进行分析,并以地闪密度空间分布与最大地闪强度空间分布的叠置作为雷电风险的主要评价指标,对徂徕山地区雷电易发区域进行研究。研究结果表明,徂徕山林场闪电密度较高的区域主要位于马头山沟以北和主峰太平顶周围。同时,结合森林雷击火灾原因、特点和地形特征,提出了一套符合实际的森林雷击火灾风险分析方法。该研究对森林雷电灾害的防护具有重要意义。In order to understand and analyze the dynamic behavior of forest lightning fire,the risk assessment of forest lightning fire was carried out.In order to reduce or avoid the losses caused by forest fire,casualties and equipment damage caused by lightning,this paper takes the monitoring data of lightning positioning system in Shandong Province,lightning monitoring data,weather and climate observation data,forest farm elevation data,geographic information data,field survey data and relevant information provided by customers from 2007 to 2018 as the basis.This paper analyzes the spatial and temporal distribution characteristics of lightning activities in mountain Cu Lai area by using various analysis methods,such as analysis method,correlation analysis,overlay analysis and buffer analysis.The overlap of spatial distribution of ground lightning density and maximum lightning intensity is taken as the main evaluation index of lightning risk,and the lightning prone areas in the area are studied.The results showed that the areas with high lightning density were mainly located in the north of Matoushan Gully and around Taiping Peak.At the same time,combined with the causes,characteristics and terrain characteristics of forest lightning fire,a set of practical forest lightning fire risk analysis method is proposed.This study is of great significance to the protection of forest lightning disaster.
