摘要
利用楚雄彝族自治州(简称楚雄州)30年(1981-2010年)年雷暴日数统计资料、云南省ADTD系统二维闪电定位资料,以及云南省地理信息高程数据中提取的坡度、海拔、海拔差数据,应用数量统计方法结合Arc-GIS制图方法,分析总结了全州雷暴时空分布规律、雷灾特征等,最后依据行业标准提取相关指标进行雷电易发区域及其防护等级划分.
Abstract
Using the statistical data of thunderstorm days in Chuxiong Prefecture from 1981 to 2010,the two-dimensional thunderstorm location data of Yunnan ADTD system from 2007 to 2016,and the slope,elevation and elevation difference data extracted from the geographic information elevation data of Yunnan Province,to ap-ply quantitative statistical method and ArcGIS mapping method,then analyze the temporal and spatial distribution characteristics of thunderstorm activity and the characteristics of thunderstorm disaster,etc.According to industry 1 standards,relevant indicators are extracted to classify thunderstorm prone areas and their protection levels.
