摘要
采用问卷调查方法,调查了公众对太湖蓝藻暴发这一风险事件相关信息的关注度,运用因子分析方法确定关注信息的类别。对调查人群进行二阶聚类分析,了解各类人群的基本特征。在统计分析影响公众关注度因素的基础上,引入风险信息交流的概念,旨在探讨提高公众风险关注度,加强风险交流的方案。研究表明,影响公众关注度的因素主要有:公众的受教育程度、获取信息的途径。相应的措施为:开展风险教育活动、拓宽风险信息的获取途径、提高风险信息交流效率。
Risk communication helps to identify and weigh the choice of policies and decisions in the risk analysis process. Using the questionnaire, the paper investigates the degree of public＇s concern about the related information of the outbreak of algae in Taihu Lake. The types of information concerned are confirmed using the factor analysis; the cluster analysis is made on the investigated groups to obtain the basic features of different groups. On the basis of the statistical analysis of the factors that affect the public attention, the concept of the hazard information exchange is introduced in order to increase the public concern and reinforce the measures of risk communications. Studies show that factors that influence the public concern mainly include the education of public and the access to information. Corresponding measures are to carry out educational activities, broaden the access to risk information and improve the efficiency of risk-information exchange.
