基于SPSS的宁夏雷电灾害特征分析和雷电灾害风险区划研究

摘要

Based on the SPSS statistical analysis system, adopting the methods of statistical analysis, correlation analysis and significance test, the lightning monitoring data from 2007 to 2011 in Ningxia and the lightning disaster data from 1998 to 2013 in Ningxia were analyzed to discuss the characteristics of lightning disaster of 5 municipalities in Ningxia and analyze the correlation between the factors such as the number of the event of lightning, lightning deaths, lightning days, lightning strike and the lightning strike density and the administrative area, the total population, the agriculture population and so on. The index and zoning of the lightning disaster risk zone regionalization are elaborated,and the research idea and the assess-ment of the lightning disaster risk index and the regionalization problems are put forward.%文章基于SPSS统计分析系统，通过对2007—2011年宁夏雷电监测资料和1998—2013年宁夏的雷电灾害资料采用统计分析和相关性分析、显著性检验的方法，探讨了宁夏5市雷电灾害特征，分析了雷击事件数、雷击死亡人数、雷电日数、雷电闪击次数、雷电闪击密度等因素与行政区域面积、总人口数、农业人口数等的相关性，阐述了宁夏雷电灾害风险区划的指标和区域划分，提出了雷电灾害风险指数的研究思路及其评估与区划问题。
