| 摘 要： | 利用1960 -2010年四川雷暴逐日观测资料分析四川雷暴特征及变化规律。结果表明，四川雷暴年平均雷暴日数呈逐年减少趋势，高原雷暴发生的日数明显多于盆地区域，川西高原南部山区偏多于川西高原北部。把研究的防御重点信息数据与地理信息系统（GIS）技术相互结合，将雷暴灾情实况、雷暴多发区域、人口、经济情况的属性信息特点进行地理编码，使其转换为包含经度、纬度、海拔等相关地理信息的地理图层shape文件，实现灾害防御数据信息与地理信息的融合。结果表明：盆地东部的南充、广安和高原的盐边为雷暴重点防御一级区域；巴中、阆中、峨眉、盐源为雷暴二级防御区域；绵阳、南充、泸州、阿坝为雷暴三级防御区域；成都、温江、都江堰、达州、遂宁、雅安、宜宾等为雷暴四级防御区域。

| Abstract: | Based on Sichuan thunderstorm daily observation data from 1960 to 2010, thunderstorm characteristics and variation of sichuan was analyzed. The results show that the number of average thunderstorm days in Sichuan was decreasing trend yearly, Plateau thunderstorms occurred significantly more than the number of days of the basin region, southern mountain area of West Sichuan Plateau was partial than northern. The study of the defense focus information data and geographic information system ( GIS ) technology combined with each other, the thunderstorm, thunderstorm disaster, population, economy, property information characteristics of geographic coding, which is converted to contain the longitude, latitude, altitude and other related geographic information geographic layer shape file, realize the disaster data information and geographic information fusion. The results show that : Nanchong, Guang'an on the east of basin and Yanbian as thunderstorms key defense level area; Bazhong, Langzhong, Emei, Yanyuan as thunderstorm two level defense area; Mianyang, Nanchong, Luzhou, ABA as thunderstorm three level defense area; Chengdu, Wenjiang, Dujiangyan, Dazhou, Suining, Ya'an, Yibin etc. as thunderstorm four defense area. |
