Abstract:
By means of the annual average thunderstorm day data, lightning location data and lightning disaster data of 10 meteorological stations in the eastern Qinghai from 1997 to 2012, the lightning location data from 2008 to 2014, and lightning disaster data from 1997 to 2014, using the number of thunderstorm days, lightning density, comprehensive disaster degree, life vulnerability modulus, and economic vulnerability modulus as vulnerability assessment indicators of lightning disasters, the vulnerability assessment model of lightning disaster is established with the weights of indexes determined by analytic hierarchy process (AHP). According to the classification method of meteorological disaster statistics, the vulnerability grades of lightning disasters are classified, and the vulnerability zoning map of lightning disasters in the eastern Qinghai is given. The results show that the vulnerability areas of lightning disasters in the eastern Qinghai exhibit a characteristic of scattered distribution; the high vulnerability areas are in Datong County, Longhua County, the second high vulnerability areas in Huzhu County in Huangzhong County, the medium vulnerability areas of vulnerability in Xining and Huangyuan County, the low vulnerability areas in Ledu District, the safe areas in Minhe County and Xunhua County.
