This research examines and compares perceptions held by laypeople and ecologists about risks to ecosystems, particularly risk from global climate change (GCC). A survey elicited perceptions of 31 risk characteristics for 13 GCC and 12 non-GCC risks to ecosystems. Factor analysis was used to examine the structure of layperson and expert risk perceptions. Both experts and laypeople tend to perceive GCC risks to ecosystems as less avoidable and more acceptable than risks from other causes. Compared to laypeople's perceptions, though, experts perceived GCC risks to have slightly lower impacts, be less avoidable, more acceptable, and less understandable than non-GCC risks to ecosystems. These findings may help guide efforts to communicate with laypeople about ecological risks from climate change.
本研究考察并比较了普通民众和生态学家对生态系统风险的认知，特别是全球气候变化（GCC）带来的风险。一项调查收集了人们对13种全球气候变化风险和12种非全球气候变化风险对生态系统造成的31种风险特征的认知。因子分析用于检验普通民众和专家风险认知的结构。专家和普通民众都倾向于认为，与其他原因造成的风险相比，全球气候变化对生态系统的风险更难以避免且更可接受。不过，与普通民众的认知相比，专家认为全球气候变化风险对生态系统的影响略小，更难以避免，更可接受，且比非全球气候变化风险更难理解。这些发现可能有助于指导与普通民众就气候变化带来的生态风险进行沟通的工作。
