选取全国范围内台风灾害中的农作物受灾面积、房屋倒损数、死亡人数、直接经济损失4个常用灾害指标,通过建立无量纲函数转换定义了全国范围内台风各个单项灾害指标的等级,并利用灰色关联度理论确定了全国范围内台风灾害综合等级划分标准.基于上述工作建立了台风灾害综合等级快速评估模型.利用此模型对2000-2007年登陆我国的台风灾害进行了评判与排序,分析结果较为合理.
選取全國範圍內檯風災害中的農作物受災麵積、房屋倒損數、死亡人數、直接經濟損失4箇常用災害指標,通過建立無量綱函數轉換定義瞭全國範圍內檯風各箇單項災害指標的等級,併利用灰色關聯度理論確定瞭全國範圍內檯風災害綜閤等級劃分標準.基于上述工作建立瞭檯風災害綜閤等級快速評估模型.利用此模型對2000-2007年登陸我國的檯風災害進行瞭評判與排序,分析結果較為閤理.

Grade division of each typhoon disaster item in China region is conducted by selecting areas of crop suffered disasters, quantity of house collapsed and damaged, amount of died people, direct economic loss and then establishing the non-dimension function transform. And by using the theory of grey association analysis, the general disaster grade division standard is confirmed. Based on the above study, a typhoon general disaster grade division model is put forward. In terms of this model,the disasters caused by typhoons landing China in 2000-2007 are compared each other, and the analysis results are reasonable.
