Abstract: Using the lightning data by ADTD from 2008 to 2011 and lightning disaster statistics from 1999 to 2008 in Hubei Province and selecting lightning strike density, strong lightning more than 50kA, lightning disaster frequency, economic loss modulus and life vulnerability modulus as lightning disaster vulnerability risk evaluation indexes, vulnerability analysis indexes are calculated for various districts of the city. The parameter which is lightning disaster frequency must be modified. Only the parameters are placed in a horizontal line, the lightning vulnerability analysis will be scientifically. They are classified into five degrees and the degree values of vulnerability of lightning disasters for each are obtained. Then, it comes to the vulnerability zoning of the lightning disaster in Hubei. The results show that: The main features of the high-risk zones are higher lightning disaster, better economic development and densely populated; while the low-risk areas are opposite. Lightning hazards is not only related to the geography, climatic environment, but also to the population density and economic development situation.
