摘要：

利用1968~2007年河北省廊坊市9个地面气象观测站的雷暴资料及1998~2007年廊坊市雷电灾情统计数据,结合其区域经济状况和人口密度,确定用雷暴日数(M)、雷电灾害频度(R)、经济(GDP)易损模数(E)、经济损失模数(E′)、生命易损模数(L)、生命损伤模数(L′)作为廊坊市雷电灾害易损性评估指标。计算出廊坊市各县(市、区)6个雷电灾害易损性评估指标后分等级进行综合评估与分析,得出各县市区的易损度,并按5级分区法对廊坊市雷电灾害易损度进行区划。结果表明:廊坊市开发区为极高易损区,全市无低易损区和极低易损区。

Abstract:

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-
ageable area. Scientific basismightbe provided for the planning of regionalprevention and reduction of lightning disaster in Langfang.

Key words: lightning disaster, vulnerability, evaluation index, vulnerability division
