[Objective]The research aimed to evaluate vulnerability of the lightning disaster in Guizhou and conduct zoning. [Method]According to data of the lightning monitoring network and statistical data of the lightning disaster in Guizhou during 2007-2012,by combining economy and population situations in 9 cities of Guizhou,6 indicators were used to assess vulnerability of the lightning disaster: CG lightning intensity,strong CG lightning intensity,annual average occurrence frequency of the lightning disaster,GDP per capita,population intensity and casualties frequency. By constructing principal component,determining weighing and comprehensive assessment,vulnerability grade of the lightning disaster in Guizhou was divided. [Result]Guiyang was extremely high vulnerability zone,high vulnerability zone included Zunyi,Bijie and Liupanshui,moderate vulnerability zone included Anshun,Tongren and Qianxinan,Qiannan was low vulnerability zone,and Qiandongnan was extremely low vulnerability zone. Vulnerability distribution boundary of the lightning disaster in Guizhou was along northeast to southwest,and vulnerability of the lightning disaster gradually weakened from northwest to southeast. [Conclusion]The research provided scientific basis for preventing lightning disaster and reducing damage of the lightning disaster.
