The definition of feature vector space for students’ network behavior and its eigenvectors model were presented.Based on the definition,fuzzy vector methods for describing college students’ network behavior were proposed and the approach for generating the fuzzy vector space of college students’ network behavior were provided.Fuzzy clustering approach was used in analysis and with this method,college students were partitioned into fuzzy categories according to their network behaviors.For different categories,advices and strategies were proposed to help college students to use the Internet efficiently,to improve their positive social communication and to establish a healthy network lifestyle.
