不同的洪灾评估方法得到的评估结果具有一定的差异,然而这些结果都具有一定的合理性,因此给科学决策带来了困难.针对这一问题,以多种方法的评估结果为分析对象,引入AHP法对各种评估结果进行权值分配,建立了基于多种评估结果的综合优化模型.对1998年各地区洪水灾害资料分析的结果表明,综合优化结果包含的信息量全面,综合了多种评估结果的特点,使评估结果更有说服力.该模型简便可靠,为洪灾评估的科学决策提供了有力的支持,同时该模型对于排序性评估也具有普遍适用性.
However, these results have some rationality and therefore bring difficulties to scientific decision-making.Aiming at this problem, taking the assessment results of many methods as the analysis object and introducing Analytic Hierarchy Process (AHP) method is used to assign the weights to various assessment results, and a comprehensive optimization model based on a variety of assessment results is established.Analysis of flood disaster data of various regions in 1998 shows that the comprehensive optimization results contain comprehensive and comprehensive information, The result of the evaluation is more convincing and the result is more convincing.The model is simple and reliable, which provides strong support for scientific decision-making of flood assessment and also has universal applicability to the ranking assessment.
