摘要
文章利用1998-2018年雷电灾害统计资料,对西藏地区的雷电灾害时空分布特征及其造成的损失进行了分析。结果表明,西藏地区在1998-2008年雷电灾害发生次数呈上升趋势,2008-2018年呈减少(或平稳)趋势;从雷电空间分布特征来看山南南部、拉萨大部和那曲西部是闪电多发区。因雷击造成人员或牲畜伤亡、家用电器和房屋损毁等均集中发生在农牧区,城镇相对较少。
The article uses the statistical data of lightning disasters from 1998 to 2018 to analyze the temporaland spatial distribution characteristics of lightning disasters in Tibet and the losses caused by them.The resultsshow that the number of lightning disasters in Tibet increased during 1998-2008,and decreased during 2008-2018(or stable)trend;from the perspective of lightning spatial trends,southern Shannan,most of Lhasa and west-ern Nagqu are lightning-prone areas.The casualties due to lightning strikes,livestock,household appliances,and house damages are concentrated in farming and pastoral areas,with relatively few in towns.
