摘　　要：为了研究渠县的洪灾等级,在综合考虑渠县经济和受灾情况的基础上,针对渠县5次特大洪灾,从经济损失、农作物受灾情况、受灾人口、死亡人口、失踪人口和房屋倒塌情况6个方面构建评价指标,先对原始数据进行无量钢化处理,再应用接近性关联模型确定洪灾灾情与极重灾的接近程度,计算渠县的洪灾灾情的关联度,最后确定渠县的洪灾灾情等级。通过实际分析,评价结果与渠县的实际灾情比较相符,能为渠县洪灾灾情等级的综合评价提供依据。In order to investigate Quxian＇s floods rating,This paper constructs an evaluation system about the economic loss,crops disaster,affected population,number of dead and missing and housing collapse based on Quxian＇s economy and disaster situation for five floods.The raw data is processed to dimensionless firstly.Then,the proximity grey correlation model is applied to determine the degree of proximity and then compute the correlation degree,so to determine the annual flood grade lastly.The result shows that our conclusion is consistent with the actual disaster fact through analysing,and thus provides the basis for comprehensive evaluation of local flood level.
