A field survey on Minjiang University City campus plants has been conducted. The results showed that the species diversity of landscape trees can meet the needs of eco-campus construction. There were 57 plant families with 146 species, up to palm plants, 14 species, followed by sankoh plants, 9 species. Trees:shrubs to 64:43, 58 kinds of ground cover plants, five kinds of bamboo, 49 kinds of native plants, accounting for 33.56% of the total species. There were 60 kinds of fouling species, accounting for 41.10% of the total species. But the campus was not enough deciduous tree species, sufficient proportion of gymnosperms and fragrant plants, bamboo plants was relatively lack, barely featured species. We need to pay more attention to campus greening purification functions, further strengthen the ecological layout.
