In this paper, the effect of sports environment on college students' physical exercise is researched. The results of the survey of 8 university students in A area show that the top three factors that affect the participation of students in physical exercise are: lack of site equipment, poor conditions; no time for exercise; no professional guidance. The results show that 50% of the university sports facilities can not meet the basic requirements of the University, too much attention to the construction of landmark venues, ignoring the balanced development of various sports venues; most of the school sports venues are insufficient, especially the lack of indoor sports venues. In the field survey, we found that the quality of the equipment consumed in the small ball project is poor, which seriously affects the effect and enthusiasm of students' classroom learning. The results of this paper have certain reference value for colleges and Universities to carry out physical exercise reasonably and effectively.
