摘要
本文根据自然灾害系统理论和自然灾害风险评估理论,利用气象资料、地理信息数据、社会经济数据以及雷电灾情等数据,采用统计方法、灾情解析、专家打分等方法,从致灾因子、孕灾环境、承灾体方面,研究雷电灾害风险评估及区划方法,建立起评价指标与风险评估的定量关系,形成了较完整的雷电灾害风险评估及区划技术方法体系,具有很好的应用推广价值。对安徽省雷电灾害风险区划表明:高风险区主要位于经济水平较高的城市以及皖南山区高海拔地区,而低风险区主要位于淮北地区,与灾情验证情况吻合。
Under the guideline of the natural disaster system theory and assessment of natural disaster risk theory,using meteorological,geo-information,social and economic,thunder and lightning disaster data,combined with statistical method,disaster analysis and expert evaluation method,this paper aims at the method of the risk zoning of thunder and lightning,and establishes the quantitative relation between the assessment indexes and the risk zoning of thunder and lightning,based on the GIS platform,considering the disaster-inducing factors,environment of breeding disasters and hazard-bearing bodies.In this way,the paper formulates a relatively complete technology system of the risk zoning of thunder and lightning which deserves being popularized.The results of risk zoning in Anhui province show that the high risk of thunder and lighting is mainly located in cities with relatively higher economic level as well as the mountainous regions with higher altitude above the sea in the south of Anhui,while the low risk is mainly located in Huaibei area.
