摘要
大规模洪涝灾害初期受灾点物资需求量大,而供应点物资储备不足。以灾情、人口和物资为指标构建郑州“7·20”洪涝物资需求紧迫度评价体系,运用层次分析–熵值法组合赋权应急物资需求紧迫度评价指标,采用B型关联-TOPSIS法确定受灾点物资需求紧迫度。结果表明:伤亡人数、物资需求量、单日降水量影响应急物资需求紧迫度较大;郑州市物资需求紧迫度最高,中牟县物资需求紧迫度最低。
In the early stage of a large-scale flood disaster, the affected areas are in great demand, while the materials reserve at the supply points are insufficient. The Zhengzhou “7·20” flood material demand urgency evaluation system was constructed with disaster situation, population and materials as indicators. Analytic hierarchy process and entropy methods are used to assign the weight of the evaluation index of the emergency material demand urgency. B-type correlation and TOPSIS methods are used to determine the urgency of material needs in the disaster sites. The results show that casualties, material demand and rainfall in a single day affect the emergency material demand urgency;The material demand urgency in Zhengzhou was the highest, and that of Zhongmou county was the lowest.
