环境中的风险认知特征

采用多维度的心理测量范式,研究公众在“影响程度”、“可控性”、“了解程度”、“影响的持续性”、“发生的可能性”、“结果的严重性”六个维度上对39个环境条目的风险认知特征。研究结果验证了“风险程度指标”,并将环境风险划分为“生态环境”“疾病与灾害”“生活环境”三个大类并探讨其风险认知特征。结果显示,由“客观认识”和“主动作用”两维度形成的认知地图可有效地指导风险沟通。

Characteristics of Environmental Risk Perception

Multi-dimensions measurement was applied to investigate the characters of 39 environmental items on six risk dimensions-- impact of risk,controllability, knowledge about risk,durability,passibility of occurrence,severity of consequences. The result confirmed the indicator of risk and divided the environmental hazards into three classes--ecological category, natural environment and disease category,and living category. Moreover, objective appraisal of risk and subjective appraisal of coping were two thinking ways to instruct risk communication.
