摘　　要：基于宾阳县国家气象站1957-2013年雷暴气候资料以及1995-2018年雷电灾害数据,应用数理统计、实证分析等方法,分析研究了宾阳县雷电活动、雷电灾害特征和雷击受损情况,探讨当地农村雷电灾害的主要成因。结果表明,近八成雷电灾害发生在农村,农村雷灾具有事故多、人员伤亡重、灾害损失大的特点;雷电灾害与雷暴发生的时数月分布规律大致相同,均在6月达到峰值,6-8月雷电活跃期与雷电灾害高发期有较好对应关系;雷电活动频繁、强度大,防雷减灾知识匮乏、防雷设施不完善等因素是造成广西宾阳农村雷电灾害的主要成因。Based on the thunderstorm climate data of 1957-2013 and the lightning disaster data of 1995-2018 from Binyang national meteorological station,the lightning activity,characteristics and damage of lightning disaster in Binyang County were analyzed,and the main causes of lightning disaster in rural areas were discussed by using mathematical statistics and empirical analysis.The results showed that nearly 80%of lightning disasters occurred in rural areas,which were characterized by many accidents,serious casualties of people,and large disaster losses.The frequency distribution rule of lightning disasters and thunderstorms was almost the same,always reached the peak in June.From June to August,there was a good corresponding relationship between the lightning active period and the high incidence period of lighting disaster.Frequent lightning activities,high intensity,lack of knowledge on lightning protection and imperfect lightning protection facilities were the main causes of rural lightning disaster in Binyang.
