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，川西高原南部山区多于川西高原北部。根据雷电分布特点将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，将其转换为包含经度、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。得出以下结论：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。

Based on Sichuan thunderstorm daily observation data from 1960 to 2010,thunderstorm characteristics and variation of sichuan were analyzed. The results showed that the number of average thunderstorm days in Sichuan was decreasing yearly,Plateau thunderstorms occurred significantly more than the number of days of the basin region,and the hunderstorm number of the southern mountain area of West Sichuan Plateau more than that in the Northern. Combined the key defence information data with geographie information system (GIS)technology,this study integrates the disaster data information with geographic information by geographical coding of the thunderstorm, thunderstorm disaster, population, economy, property information characteristics, which are converted to the geographic layer shape file containing the longitude, latitude, altitude and other related geographic information. It is found that:the first defense level areas of thunderstorms are Nanchong, Guang'an on the east of basin and Yanbian;the second are Bazhong,Langzhong,Emei, Yanyuan;the third are Mianyang,Nanchong, Luzhou,ABA;and the forth are Chengdu,Wenjiang, Dujiangyan, Dazhou, Suining, Ya' an, Yibin etc.
