At present, the studies and social adaptation problems of impoverished undergraduates have arisen concerns of the whole society. The proportion of college students’ dropout, crime and abnormal psychology due to poverty is increasing. Thus more social support to impoverished undergraduates can not only reduce or eliminate the above problems, but also reflect education equity of a country or society. This paper investigates and analyzes the degree of social support and the psychological health level of impoverished undergraduates by The Symptom Checklist90(SCL-90) and Social Support Rating Scale(SSRS). The results show that: (1) There are more psychological pressure in impoverished undergraduates. (2) Social support to impoverish undergraduates is positively correlated to their psychological health level. (3) Female college students are better than male students at the use of social support, and the former receive more social support.
