基于闪电定位资料的四川省雷电风险区划分析

本文通过应用2005～2012年四川省闪电定位资料、四川省各地市州经济发展状况、人口分布情况等资料,采用数理统计分析方法,分析了四川省雷电风险区划.研究得到以下结论：（1）四川省中部平原地区和丘陵地带属于四川省雷电高风险区域,川东南地区属于雷电中等风险区域,川西高原及四川东北部地区属于低风险区.（2）四川省平原地区和丘陵地区相较其他地区经济较为发达,人口密集程度也较高,且位于雷电高发地区,易导致雷电灾害发生.（3）川西北高原地区由于地广人稀,经济发展较差,受高原气候环境影响等因素,不易形成严重的雷电灾害。

Analysis of Sichuan Province Lightning Risk Zoning Based on Lightning Location Data

This paper using the mathematical statistics method to analyzes Sichuan Provincelightning risk zoning by adopting the Sichuan Province lightning location data from 2005＂to 2012, the city＇s economic and population distribution. The result shows that high lightning risk area is the central plain and hills of Sichuan Province, the medium lightning risk area is southeast area of Sichuan Province, the low risk area is the Western Sichuan Plateau and northeast area of Sichuan Province. Sichuan plain area and hilly area are developed area, have higher population density, located in the high lightning risk areas, the strong thunderstorm weather can easily lead to lightning disaster. Northwest Sichuan Plateau area due to much land and few people, poor economic development, plateau climate, could not easily lead to serious lightning disaster.
