According to the date of thunderstorm-day from1968 to 2007 and lightning disaster statistics data from 1998 to 2007 in Langfang, combined with its economic status and population density, vulnerability analysis, evaluation and vulnerability division of lightning disaster aremade. Four indices are selected to evaluate the vulnerability of lightning disaster in Langfang, including annual mean thunderstorm days (M), lightning disaster frequency (R), economic vulnerabilitymodule(D), economic lossmodulu(D), vital vulnerabilitymodule(L) and life and injurymodulus (L’). Based on them, the vulnerability assessmentstructure of thunderstorm disasters in each counties ofLangfang are given. Then, the vulnerability assessment indices of thunderstorm disasters are classified as five gradeswith given values. The comprehensives vulnerability assessment indices of these nine counties are also graded as corresponding five degrees. Finally, vulnerability division of the lighting disaster is obtained based on the vulnerability degree values of the nine counties in Langfang. The result shows thatKaifaqu and Guangyang districtbelong to themaximal damageable area, Xianghe county, Bazhou city, Sanhe city, AncidisrictandGu’an county belong to the high damageable area.The restcounties belong to themedium dam-
