摘　　要：蓝藻水华暴发已成为全球性生态环境问题。太湖作为流域重要的水源地,2007年蓝藻水华事件的暴发引起公众的高度关注。运用问卷调查法,研究无锡市区489名公众的太湖蓝藻水华生态风险感知特征及其主要影响因素。研究结果表明:蓝藻水华生态风险被公众知觉为总体风险是陌生和完全可控的;蓝藻水华暴发原因是陌生和不可控的,这是引起公众风险意识的主要因素。影响公众蓝藻水华生态风险感知水平的主要因素有媒体、信息和个体因素。报纸广播电视是主要的媒体因素。信息因素有灾害信息、灾害治理信息、政府防范措施信息。灾害治理信息的影响作用最大,其次是灾害信息和政府防范措施信息。不同性别、年龄段、教育程度、收入水平及职业的人群,对不同类别的风险信息关注程度不同,影响到个体风险偏好的不同。研究结果有助于决策者更全面地理解蓝藻水华风险的本质,开展风险沟通,针对不同特征的人群选择有效的风险管理方案。Cyanobacterial bloom has become a global problem. Taihu, fed by the Yangtze River, provides drinking water for more than 2 million people. Cyanobacterial Bloom Incident in Wuxi City in 2007 attracted much public attention. To investigate Chinese people＇s ecological risk perception characteristics of eyanobacterial bloom of Taihu Lake and the main factors which influenced these characteristics, 489 people from Wuxi city in China were surveyed. The results indicated that the overall characteristic of public perception was＂strange＂and＂eontrollable＂. The outbreak reason was＂strange＂and＂uncontrollable＂which was the main factor to cause the public risk awareness. Media, information and individual factors were the main three influence factors. Newspapers,radio and television were the major media. The information factors included the disaster information（DI）, the disaster control information（DCI）and the information on preventive measures from government（PMGI）,among which,DCI played the greatest role,followed by the DI and the PMGI. Public had the different risk preferences among the different gender, age, educational level,income levels and occupational groups. And they showed a different concern about the different risk information. The results were helpful for decision-makers to risk, provide service for risk communication and choose teristic of the target population. understand the nature of the cyanobacterial bloom effective management tools according to the characteristic of the target population.
