摘　　要：为了减少四川省攀西地区复杂的地形环境下森林雷击火灾带来的危害,从雷电强度、雷电密度、海拔和土壤电阻率4个致灾因子出发,并以空间栅格为格点,采用AHP算法和GIS相结合的方法,对攀西地区森林火灾高危区进行雷击火灾风险分析和区划研究。结果表明:攀西地区雷电致灾危险性极高风险主要分布在木里藏族自治县东南部和西南部、冕宁县中部和东部、盐源县西北部和盐边县中部;高风险区主要分布在木里藏族自治县北部和东部、冕宁县南部和东部、喜德县西部和南部、西昌市北部、德昌县北部和西部、盐边县北部、米易县北部、仁和区北部;只有少部分较低风险区主要分布在宁南县中部和东部、会东县东部、会理县南部、昭觉县东部;其余地区均为一般风险区。In order to reduce the harm caused by forest lightning fires in the complex terrain environment of Panxi region,Sichuan Province,starting from four disaster factors:lightning intensity,lightning density,altitude,and soil resistivity,and using spatial grids as grid points,a combination of AHP algorithm and GIS method was used to conduct lightning fire risk analysis and zoning research on high-risk areas of forest fires in Panxi region.The results showed that the extremely high risk of lightning disaster in Panxi area was mainly distributed in the southeast and southwest of Muli Zang Autonomous County,the middle and east of Mianning County,the northwest of Yanyuan County and the middle of Yanbian County;High risk areas were mainly distributed in the north and east of Muli Zang Autonomous County,the south and east of Mianning County,the west and south of Xide County,the north of Xichang,the north and west of Dechang County,the north of Yanbian County,the north of Miyi County,and the north of Renhe District;Only a few low-risk areas were mainly distributed in the middle and east of Ningnan County,the east of Huidong County,the south of Huili County,and the east of Zhaojue County;The other regions were all general risk areas.
