洪水是对生命和财产最常见、分布最广的自然风险之一。有必要确定洪水易发地区的风险，以支持风险管理决策，从高层次的规划建议到详细的设计。有许多方法可用于进行此类研究。其中最被接受，因此也是最常用的是基于计算机的淹没图绘制。相比之下，脆弱性评估的参数方法越来越被接受。对于决策者来说，这些方法各有优缺点，本文重点介绍了这两种方法在使用中的比较。得出的结论是，参数法（这里是FVI）是评估洪水脆弱性的唯一方法;而确定性方法虽然对脆弱性的评估有限，但具有更好的科学基础。(c)2012爱思唯尔有限公司保留所有权利。
Floods are one of the most common and widely distributed natural risks to life and property. There is a need to identify the risk in flood-prone areas to support decisions for risk management, from high-level planning proposals to detailed design. There are many methods available to undertake such studies. The most accepted, and therefore commonly used, of which is computer-based inundation mapping. By contrast the parametric approach of vulnerability assessment is increasingly accepted. Each of these approaches has advantages and disadvantages for decision makers and this paper focuses on how the two approaches compare in use. It is concluded that the parametric approach, here the FVI, is the only one which evaluates vulnerability to floods; whilst although the deterministic approach has limited evaluation of vulnerability, it has a better science base.
