了解减轻洪水的行为很重要，因为欧洲和全世界正在转向基于风险的洪水管理方法，这些方法设想易受洪水影响的家庭为减少风险作出贡献。近年来有关影响防洪行为因素的文献表明，洪水应对评价是理解和解释防洪行为的重要变量。应对评价源于保护动机理论（PMT），是指人们在评估自身规避某种风险的能力时所经历的认知过程。然而，关于应对评价重要性的实证文献仍然很少，特别是应对评价的三个单一组成部分对预防行为的独立影响，即反应效能、自我效能和反应成本，我们所知甚少。本研究介绍了最近对莱茵河沿岸752个易受洪水影响的家庭进行的一项调查的结果，以便详细了解洪水应对评估的组成部分对四种不同类型的洪水缓解行为的影响：结构建筑措施、适应性建筑使用、防洪屏障的部署和购买洪水保险。结果证实，洪水应对评估是预防行为方面的一个重要变量。特别是，响应效能和自我效能都有助于解释四种不同类型的洪水缓解行为的模型。基于这些发现，得出的结论是，风险沟通应更加注重有效减少或避免洪水损害的减灾措施的潜力，以及如何在实践中实施这些措施的信息。(C) 2013 Elsevier Ltd.版权所有。
Insights into flood mitigation behaviour are important because of the ongoing shift to risk-based flood management approaches in Europe and worldwide, which envisage a contribution from flood-prone households to risk reduction. The recent literature on factors that influence flood mitigation behaviour indicates that flood-coping appraisal is an important variable to understand and explain flood mitigation behaviour. Coping appraisal originates from Protection Motivation Theory (PMT), and refers to the cognitive process that people undergo when evaluating their own ability to avoid a certain risk. However, the empirical literature on the importance of coping appraisal is still scarce, and, in particular, little is known about the independent influence of the three single components of coping appraisal on precautionary behaviour: namely, response efficacy, self-efficacy, and response cost. This study presents the results of a recent survey among 752 flood-prone households along the river Rhine in order to provide detailed insights into the influence of the components of flood-coping appraisal on four different types of flood mitigation behaviour: structural building measures, adapted building use, the deployment of flood barriers, and the purchase of flood insurance. The results confirm that flood-coping appraisal is an important variable in terms of precautionary behaviour. In particular, both response efficacy and self-efficacy contribute to the models which explain the four different types of flood-mitigation behaviour. Based on these findings, it is concluded that risk communication should focus more strongly on the potential of flood-mitigation measures to effectively reduce or avoid flood damage, as well as on information about how to implement such measures in practice.
