For effective communication and management of disaster risks, it is important to explore how media exposure and disaster experience related to earthquake events affect residents' prospect ranks of disaster risk perceptions. Using survey data from 327 households located in the Wenchuan and Lushan earthquake regions in China, the ordinary least square method was used to explore the associations among media exposure, severity of disaster experience, and residents' perception of prospect ranks of the possibility and severity of disasters. The results showed the following. (1) Rural households relied predominately on television broadcasts from traditional media, and on mobile phones and internet content from new media to obtain disaster information. From the residents surveyed, 90% believed that a disaster experience was serious, 82% considered that another major earthquake would seriously affect their lives and property, while approximately 40% of the residents did not believe there would be another major earthquake in the next 10 years. (2) Media exposure was negatively correlated with the perceived prospect ranks of the probability and severity of disasters, with traditional media exposure significantly negatively correlated with the perceived prospect ranks of the severity of disasters and new media exposure significantly negatively correlated with the perceived prospect ranks of the probability of disasters. Severity experience was significantly and positively correlated with the perceived prospect ranks of the probability and severity of disasters. (3) New media exposure moderated the relationship between residents' disaster experience and their perception of prospect ranks of the severity of disasters. This study can help deepen our understanding of disaster risk communication and better guide the practice of disaster risk management.
为了有效地进行灾害风险的沟通和管理，探讨媒体接触和与地震事件相关的灾害体验如何影响居民对灾害风险感知的预期等级是很重要的。本研究使用了来自中国汶川和芦山地震地区的 327 户家庭的调查数据，采用普通最小二乘法探讨了媒体接触、灾害体验严重程度与居民对灾害可能性和严重程度感知的预期等级之间的关系。结果表明：（1）农村家庭主要通过传统媒体的电视广播和新媒体的手机和网络内容获取灾害信息。在所调查的居民中，90%的人认为灾害体验是严重的，82%的人认为另一场大地震将严重影响他们的生活和财产，而大约 40%的居民不相信未来 10 年内会发生另一场大地震。（2）媒体接触与对灾害可能性和严重程度的预期等级呈负相关，传统媒体接触与对灾害严重程度的预期等级显著负相关，新媒体接触与对灾害可能性的预期等级显著负相关。灾害体验与对灾害可能性和严重程度的预期等级呈显著正相关。（3）新媒体接触调节了居民灾害体验与对灾害严重程度预期等级之间的关系。本研究有助于加深对灾害风险沟通的理解，并为灾害风险管理实践提供更好的指导。
