摘　　要：利用重庆市闪电定位系统和人工观测雷暴资料(2009-2011年)及其对应的12121气象信息电话拨打次数,运用信息扩散理论、数理统计等方法,重点对比分析闪电定位系统和人工观测雷电天气关注度.结果表明:雷电天气的关注度随其风险加大而增加,且存在季节差异;相同风险水平的雷电天气关注度,其人工观测高于闪电定位系统;基于闪电定位系统的各季雷电天气关注度高低顺序为春、夏、秋、冬,而人工观测为秋、春、夏、冬;基于信息扩散理论的雷电天气关注度都能客观反映实际,而闪电定位系统优于人工观测(基于闪电定位系统的春秋雷电天气关注度优于人工观测;而冬夏则相当).Based on the theory and methods of information diffusion of fuzzy mathematics and mathematical statistics ,we used the dialing numbers of weather service phone （named 12121） and data of LLS （lightning location system ） and lightning day manually recorded from 2009 to 2011 in Beibei of Chongqing to make a comparative analysis of the lightning weather attention degree of the general public based on LLS and manual record .The results indicated that the attention degree of lightning weather of the public increased as the attention degree risk grade （dialing numbers of phone） increased ,and a seasonal difference was detected .Lightning weather attention degree based on manual record is higher than LLS in spring and autumn and they are almost the same in summer .The LLS-based attention degree of lightning weather was the highest in spring ,followed in order by summer ,autumn and winter ,while the manual record-based attention degree of lightning weather was the highest in autumn ,followed in order by spring ,summer and winter .It is concluded that the attention degree based on information diffusion can well reflect the actual situation and that the result based on LLS is better than that based on manual record .More specifically ,in spring and autumn the result based on LLS is better than that based on manual record ,but they are comparable in summer and winter .
