[目的/意义] 探讨在突发公共卫生事件情境下，大学生的信息需求有何变化、不同信息需求类型的重要程度及其被满足的程度（以下简称"满足度"），揭示满足度高和低的信息特征。[方法/过程] 首先通过初步调查，识别在突发公共卫生事件情境下大学生的信息需求类型，包括与疾病相关、自身相关、社会相关和学校相关的信息。基于此开展问卷调查，收集556份有效问卷，厘清各层面信息需求所包含的类别。[结果/结论] 研究发现，面对突发公共卫生事件，大学生优先需要的信息主要涉及疾病的预防治疗和发展、政府应对措施、事件对学习生活的影响；满足度高的信息类型具有数据量化、流程清晰、表述明确、信息源权威、采用声像信息源等特征；满足度低的信息类型多具有不确定性、影响因素复杂、信息笼统、缺乏权威信息源等特征。研究结果一方面有助于在突发公共卫生事件情境下更好地为大学生提供更为精准的信息服务；另一方面，也可为政府在疫情信息管理和发布上提供参考，更好地满足大学生的信息需求。
[Purpose/significance] This study aims to explore the change of information needs of college students, the importance of different information needs, and the extent their information needs are satisfied under the circumstances of public health emergencies (PHE). The study further identifies features of information satisfied at high and low level.[Method/process] Through preliminary investigation, this study identified the types of college students' information needs in the context of PHE, including disease-related, self-related, social related and school related information. Totally 556 valid questionnaires were collected.[Result/conclusion] The results indicate that under the PHE, college students need different types of information, including disease prevention, treatment and development, government actions, and the impact of events on learning and life. The information students are highly satisfied has some salient characteristics, such as quantification, clear expression, authoritative information source, and audio-visual information source; the information not satisfied is usually uncertain, complex, unclear, and lack of authority information source. The results can help provide more accurate information for college students in the context of PHE. It can also inform the government in the management and release of PHE-related information, for better meeting the information needs of college students.
