摘要
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。
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.
