Abstract: In order to build an ecological campus reasonably and analyze the greening situation of the campus, the field survey method was used to investigate the campus plants in the Caishi Campus of Shandong Urban Construction Vocational College, and the diversity of plants, the composition of families and genera, key protected plants and plant landscape of the campus were analyzed. Through this survey, we have found out the current situation of plant resources and greening in the campus. The survey found that there are 123 species of seed plants（including varieties, forms and cultivated types） in the campus, belonging to 47 families and 81 genera, including 12 species of gymnosperms in 6 genera of 3 families and 111 species of angiosperms in 75 genera of 44 families; There are 11 kinds of key protected plants in the campus. At the same time, it is found that there are abundant flowering plants and distinct seasonal characteristics on campus. Compared with other universities in Shandong Province, Shandong Urban Construction Vocational College is rich in species density. But there are some problems in campus greening, such as the single plant landscape configuration structure and the insufficient construction of campus plant landscape space. Aiming at these problems, this paper puts forward feasible suggestions for campus plant resources protection and greening.
