| 摘 要： | 如何表达风险值估计不准,是深层次风险区划研究的问题.将模糊风险研究引向自然灾害风险区划领域,探讨了风险值估计不准条件下自然灾害风险区划的图型模式.给出了一种带有“层次“结构的“多值的“的自然灾害风险区划图图型模式.这是应用软计算的思想和方法得到的一种自然灾害风险区划图,我们称之为自然灾害软风险区划图.自然灾害软风险区划图不仅提供了表达风险值估计不准这一信息,而且提供了风险信息的可靠性,为改进自然灾害风险区划提供一种新的思路.

| Abstract: | It is a deep-seated problem that how to express the imprecision of risk assessments.This paper introduces fuzzy risk into the field of natural disaster risk mapping,and explores the pattern of natural disaster risks under the conditions of imprecision of risk assessments.This paper gives a kind of risk map of natural disasters with hierarchy and multiple values.This kind of risk map is called soft risk map due to that it is achieved by using the idea and method of the soft computing.Soft risk map of natural disasters not only can express the imprecision of risk value estimates,but also can express the reliability of risk information.This study will offer a new idea for the upgrade of risk maps of natural disaster. |
