【摘要】 根据气象灾害影响程度,分析了现行灾害评估中的缺陷,提出了定量评估的模糊评判法,将气象灾害造成的人员伤亡、生态环境破坏、直接经济损失、效益损失、救援损失、恢复重建等评估指标折算为精确化损失指数,归结了气象灾害损失评估的定量计算公式,并采用灾度指数和灾损等级作为气象灾害损失的相对度量指标。最后给出了一个损失评估应用实例,验证了评估方法的有效性。更多还原

【Abstract】 According to meteorological disasters,the existing deficiencies in the current disaster assessment were analyzed.The fuzzy evaluation method in the quantitative assessment was proposed.The casualties caused by meteorological disasters and ecological damage to the environment,direct economic losses,efficiency losses,rescue losses,reconstruction and other assessment indices were converted into more accurate indicator of loss index.The quantitative formula of the meteorological disaster damage assessment was summarized.The disaster damage grade and damage index were used as the relative assessment indices of weather disaster losses.Finally,a damage assessment application example was given to verify the validity of the assessment methods.更多还原
