Abstract：The content of risk assessment of regional lightning strike is introduced,including preliminary survey and application of lightning location data,and the standard for sub‑region delineation and the model of risk assessment of regional lightning strike are evaluated. Besides,a chemical industry park in Shanghai is taken as an example to introduce the basic information of the project,characteristics of lightning environment and delineation of sub‑regions,and the degree of membership of assessment indicators and the calculation result of the risk value of regional lightning strike are given. A detailed understanding of the basic information of the project is required for risk assessment of lightning strike through various ways such as site investigation and questionnaire,sub‑regions shall be delineated according to the characteristics of lightning distribution,and the risk assessment of regional lightning strike shall be conducted.

Key words：risk assessment of regional lightning strike;lightning location data;sub‑region; chemical industry park;assessment model;risk factor;regional ground flash density;assessment indicator

摘　要：介绍区域雷击风险评估相关内容，包括项目前期勘测、闪电定位资料应用、评估子区域划定标准和区域雷击风险评估模型；以上海某化工园区为例，介绍项目基本情况、雷电环境特点、子区域划分，给出评价指标隶属度及区域雷击风险值的计算结果；提出在区域雷击风险评估时，应尽可能通过现场勘测、调研问卷等多种形式详细了解项目基本情况，并结合雷电分布特征详细划分子区域，开展区域雷击风险评估。
