Abstract:
Seven mainly meteorological disasters might threaten 2008 Beijing Olym pic Game, which are lightning, hailstone, gale, high temperature, rainstorm, fog and haze. A suit of index system is set up to analyze the ability of risk contr ol and risk tolerance of the meteorological disaster in Beijing Olympic Game. Th e grade value of index system is given by experts, and the weight coefficients a re calculated by using the analytical hierarchy process. The results show that it is most frangible when Beijing encounters high temperature disaster and rains torm disaster. If lightning disaster and fog disaster occur, Beijing is medium f rangible. When hailstorm disaster and haze disaster happen in Beijing, it is rel atively frangible. Beijing is least frangible if haze disaster takes place. The analysis of vulnerability zoning shows that city region, Haidian district and Ch aoyang district are the most frangible area. Fengtai district, Fangshan county, Shijingshan district, Changping district, Shunyi county and Daxing county belong to the moderate frangible area. The other sites belong to low frangible area.
