| 摘 要： | 针对近20年北京地区发生的大风和暴雨灾害,应用灰色关联度方法,计算北京地区近20年的19个大风和暴雨灾例的灾情评估指标与关联度,进行损失评估和比较。结果表明,该方法对灾情等级划分和灾情损失排序是合理的,比较符合实际对灾情的评价,能够对不同气象灾害和同一级别的气象灾害灾情差异尺度做比较,是能够应用于实际工作中的一种科学方法。

| Abstract: | The grey correlation degree is a measure of relation among various factors,can be used to evaluate natural disaster loss.By using the grey correlation degree method,the disaster loss assessing indexes and correlation degrees of 19 severe weather events(strong winds and heavy rainfall) are calculated.The results show that the grey correlation method is reasonable in the grading of disaster situation and the ranking of disaster loss correlation degree,with the results basically in agreement with the actual situation,being applicable for natural disaster evaluation.It can identify the disaster lost difference among different meteorological disasters,as well as the differences among the meteorological disasters of the same class.It can be used to the operational disaster loss evaluation service. |
