摘要：

基于2008—2016年黑龙江省ADTD闪电定位数据，利用反距离权重插值法和Pearson相关分析法，研究了地闪密度、地闪强度、绕击率和反击率的空间分布特征，分析了黑龙江省不同防雷类别的直击雷防护效率。结果表明：地闪密度和地闪强度的空间分布呈负相关，相关系数为-0.608；绕击率和地闪密度呈正相关，与地闪强度呈低度负相关；反击率地闪密度呈低度负相关，与地闪强度均呈显著正相关。黑龙江省不同防雷类别直击雷防护保护范围内的绕击率分别为0.04%、0.71%和4.59%，即第一、二、三类防雷类别直击雷防护效率分别为99.96%、99.29%和95.41%。按照《建筑物防雷设计规范》计算第一、二、三类防雷建筑物的安全距离时，将会分别存在3.16%、4.64%和7.32%左右发生反击的风险。

Abstract:

Based on lightning location data in Heilongjiang province, the spatial distribution characteristics of ground flash density, ground flash intensity, shielding failure rate and counterattack rate were studied and the protection efficiencies of the different types of direct lightning were analyzed by using IDW and Pearson correlation analysis method.The results show that the spatial distributions of ground flash density and intensity are negatively correlated and the correlation coefficient is -0.608.The shielding failure rate is positively correlated with the ground flash density but is negatively correlated with the ground flash intensity.The counter-attack rate is negatively correlated with the ground flash density and is positively correlated with the ground flash intensity.In addition, the shielding failure rates of the first, second and third types of lightning protection buildings in Heilongjiang province are 0.04%, 0.71%, and 4.59%, meaning that the lightning protection efficiencies of three types of direct lightning protection buildings are 99.96%, 99.29%, and 95.41%, respectively.Besides, when the safety distances of the lightning protection buildings are calculated according to the design norm for protection of structures against lightning, the risk of counterattack of the first, second and third types of lightning protection buildings will reach 3.16% 4.64% and 7.32%, respectively.
