摘要:
基于河池市10个气象台站1960~2013年的雷暴日数据观测资料,分析了河池市雷暴日数的时空分布特征,同时利用对雷灾有影响的孕灾环境敏感性、致灾因子危险性、承灾体易损性及防灾抗灾能力四个因子构建雷击灾害风险评价模型,对雷击灾害风险进行区划。结果表明:河池市年雷暴日数有下降趋势,下降倾向率为4.224 d/10a;雷暴日数存在明显的季节差异,春夏季是雷暴多发季节,占全年雷电总日数的86%;雷暴日数存在多个时间尺度变化规律,在25年、15年时间尺度上,显示出强周期位相结构。河池南部的都安、大化县及西南部巴马县是雷击灾害高风险区。
Abstract:
Based on the thunder daily observation data from 1960 to 2013 of 10 meteorological stations in Hechi, the spatial and temporal distribution characteristics of lightening in Hechi was analyzed and the disaster risk regionalization was made by using the index of sensitivity of disaster-inducing environment, risk of disaster-inducing factors, vulnerability of hazard-affected bodies and disaster prevention and resilience. The result show that:the lightening days presents decreasing by the rate of 4.224 d/10a; the seasonal variation is obvious with more in spring and summer which accounts for 86% in total; The days of thunder shows strong period pattern in 15years and 20 years. The counties of Duan, Dahua and Bama are the high risk area of lighting.
