【摘要】 对1959—2008年10月山东各地雷电日数进行了分析,以山东的地貌特征、雷电发生的频率、人口密度和十一运会赛事场馆所在区域为评价因子,采用模糊数学方法分别计算出不同区域的孕灾环境敏感度、灾害发生的危险性和城市脆弱性3种指数,建立了山东地区十一运会期间雷电灾害风险评估模型,并在此基础上客观地划分等级,最后得到了山东地区十一运会期间雷电灾害的风险分级及其区划。更多还原

【Abstract】 The number of lightning days in Shandong in October from 1959 to 2008 is analyzed.Based on the landform characteristics of Shandong Province,the frequency of lightning,the density of population in Shandong,and sports events of the 11th Chinese National Games,by means of the fuzzy mathematic method,the sensitivities of disaster environment,the risks of disasters occurrence,and the vulnerabilities of the city for different areas are calculated,and the risk assessment model of lightning in Shandong for the 11th Chinese National Games is established.Whereby the grades are divided objectively,and the risk grades and regionalization for the 11th Chinese National Games in Shandong are obtained.更多还原
