德阳市多次发生旱灾,对其经济以及农业生产带来严重的影响。该文从脆弱性角度出发,从敏感性和恢复性2个方面选取指标体系,采用层次分析法和变异系数法相结合的组合赋权法确定权重,采用加权综合评分法构建评价模型,对德阳市以及市辖的6个区(县、市)旱灾脆弱性进行区划。分析表明,该方法具有普遍性、客观性和可靠性,在农业旱灾脆弱性评价中具有广泛应用价值,也为决策者提供了科学依据。
The drought in Deyang City has caused serious impacts on its economy and agricultural production. This paper, from the perspective of vulnerability, selects the index system from two aspects of sensitivity and recovery, uses the combination weighting method of AHP and CVA to determine the weight, and constructs the evaluation model by weighted synthetic score method. As well as the six districts (counties and cities) under the jurisdiction of the Municipality. The analysis shows that this method is universal, objectivity and reliability, has extensive application value in the evaluation of agricultural drought vulnerability, and also provides scientific basis for decision makers.
