Abstract: Employment pressure and social adaptation is an important focus in the mental health education for undergraduates, which is highly concerned and valued by the government, universities and the society. In order to grasp the hot areas and development context of research on domestic college students' employment stress and social adaptation, literature-based measures and a social complex network visualization tool Gephi were used to analyze the literature on the related keywords in CNKI. The results show: （1）Dissertations accounted for a high proportion of literature.（2）Through the cluster analysis of high-frequency keywords, we find that there are five major associations with "college students", "employment pressure", "social adaptability", "college graduates" and "employment problems", but the connections among the keywords are not close enough.（3）According to the co-author network study,Tang Liang's team tends to focus on psychological pressure and mental health education for college students, while Wang Gang's team tends to social adaptability of college students.（4）Research areas and universities are unevenly distributed, mainly in the southern and eastern provinces and third- tier universities.（5）The lack of social adaptability is an important reason for the employment
pressure of college students. That is, the weaker the social adaptability of college students is, the greater the employment pressure is. Inaddition, there is a significant negative correlation between the ability to adapt to study and the ability to adapt psychologically to theemployment pressure.

Key words: employment pressure, social adaptation, visualization, college graduates
