摘　　要：文章利用安徽省2010—2022年闪电定位监测数据及马鞍山市1956—2014雷暴日资料,运用雷电风险理论,构建了古树名木雷击风险计算模型,经计算得出结论:雷击银杏树产生的人身伤亡损失风险较大、自然文化遗产损失风险较小。银杏树遭受雷击物理受损的概率较低,但有雷雨天气发生时,在树下躲避的人身安全风险较大,可采用警示标语提醒、雷电预警及在通道下铺设沥青等方法防范雷电事故,以期研究结果能为国内古树名木的防雷工作提供借鉴。The article uses lightning location monitoring data from Anhui Province from 2010 to 2022 and thunderstorm day data from Maanshan City from 1956 to 2014,and applies lightning risk theory to construct a lightning risk calculation model for ancient and famous trees.After calculation,It is conduded that the risk of personal injury and loss caused by lightning strikes on ginkgo trees is relatively high,and the risk of loss of natural and cultural heritage is relatively small.The probability of physical damage to ginkgo trees caused by lightning strikes is low.However,during thunderstorm weather,the personal safety risk of avoiding under trees is relatively high.Warning signs,lightning warnings,and laying asphalt under passages can be used to prevent lightning accidents.It is expected that the research results can provide reference for lightning protection work of ancient and famous trees in China.
