Vulnerability Analysis, Evaluation and Vulnerability Zoning of Lightning Disaster in Beijing

摘要

With 1995-2005 lightning disaster data , 1995-2002 flash density data in Beijing , economic and population data, lightning strike density, lightning disaster frequency economic loss rate and population exposed to lightning disaster are selected as vulnerability evaluation indexes. Based on detailed valuation of different districts in Beijing, a comprehensive evaluation of the weakness and vulnerability of lightning disaster in Beijing is made and the vulnerability degree of lightning district is calculated. By means of the vulnerability degree above, Beijing vulnerability zoning about lightning disaster is made, which provides scientific basis for the planning of regional lightning disaster prevention and reduction in Beijing.
