| 摘 要： | 自然灾害风险度综合评价是一种影响因素较多的、复杂的系统工程.基于集对原理提出了自然灾害风险度评价新方法--集对分析法(SPAM).SPAM考虑标准分类的模糊性,避免直接确定联系度中差异度(分量)系数.SPAM概念清晰,结构简单,计算简洁,评价结果可信.以全国各省自然灾害资料为例,探讨集对分析法在自然灾害风险度评价中的应用,研究表明,SPAM是可行而有效的. |
| 关 键 词： | 自然灾害 风险度评价 集对分析 联系度 |

| Abstract: | A new approach of natural disaster risk degree assessment, Set Pair Analysis Method (SPAM) has been suggested. The method takes the fuzzy of grade standards into full account and avoids the values of discrepancy uncertainty coefficient. It is simple for concept, calculation and application, and the results of evaluation are feasible. The natural disaster risk degree assessment of all provinces in China has been researched. The results have shown that the presented method is satisfied. |
| Keywords: | natural disaster risk degree assessment set pair analysis connection degree |
