摘　　要：基于青岛的地理位置及气象历史数据,分析了2018年上合峰会举办地青岛的雷暴气候变化规律及闪电的时空分布特征、峰会核心区内2007~2016年雷电流幅值累积概率分布,定量表征了该区域雷电流活动的强弱。得到的青岛地区雷电流幅值—概率拟合曲线表达式可用于计算不同雷电流幅值的累积概率,为雷电防护工程设计提供一定依据。根据峰会核心区内雷电流幅值年最大值的平均值,计算了雷击点与屏蔽空间距离不同时,场馆处无衰减的磁场强度值,为峰会场馆及内部电子信息系统设计提供参考。有力保障了峰会的顺利举办。This paper analyzes the climate change pattern of thunderstorms in Qingdao and the temporal and spatial distribution characteristics of lightning,based on the geographical location and meteorological historical data of Qingdao,where the SCO Summit 2018 was held.By analyzing the cumulative probability distribution of lightning current amplitudes in the core area of the summit from 2007 to 2016,it quantitatively characterizes the strength of lightning current activities in this area.The lightning current amplitude-probability fitting curve expression in Qingdao can be used to calculate the cumulative probability of different lightning current amplitudes,so as to provide a certain basis for the design of lightning protection engineering.The magnetic field strength value without attenuation at the building is also calculated,according to the average annual maximum lightning current amplitude in the core area of the summit,so as to provide reference for the design of the summit venue and its internal electronic information system,and provide a strong guarantee for the success of the summit.
