Abstract: Networking has become a lifestyle for the college students. But because of its dual nature, the negative effects of network media on social life are inevitable, which makes it imperative to guide university students to adapt to the society with network media. In the new era, the education of college students' media literacy must focus on three aspects. Firstly, the alienation of college students' network behavior has resulted in the loss of their social identity and in the fragmentation of their personalities. Secondly, the lack of network behavior constraint mechanism has impinged on the building of their moral standards. Thirdly,the negative external effects of the network media are eroding college students'physical and mental health. To strengthen education of college students' network literacy, we must establish a multidimensional education model with focus on cultivating college students' network ethics and sense of responsibility and a rational attitude towards network using. Educators must also promote their network literacy so that they can play a competent role in college students' media literacy education. To ensure the effect of media literacy education, it is necessary to optimize network ecology and reduce the risk of negative impact of network environment on media literacy education

Key words: networking, college students, network media, media environment, media literacy education
