Based on ethnology theory, sociology and other subject perspectives, starting from cases of sample questionnaire and network of college students'national consciousness, it analyzes the basic characteristics of college students'national consciousness. Then, review the historical changing track of college students'consciousness Since the reform and opening time, and analyze the obsessional factors of college students'consciousness; and then, generalize some ordinary guiding and cultivating strategies. Taking the education of outlook on nation in Guangxi University for Nationalities for an example to introduce the facilitation experience of college students'national consciousness in national institutions. This provides effective reference to guiding and cultivating college students'national consciousness.

本文坚持以马克思主义的世界观和方***作指点，立足于民族理论、社会学等学科视角，从大学生民族意识的现实抽样问卷与网络表达的个案调查入手，剖析大学生民族意识的基本特性，接着，归顾改造开放以来大学生的民族意识历史演化轨迹并剖析大学生民族意识的现实困扰因素；入而，归纳普通院校大学生民族意识导育策略，并以广西民族大学民族观教育为例介绍民族院校的大学生民族意识导育经验，以期对高校大学生民族意识导育工作提供有效的借鉴。
