Abstract: In order to grasp the species composition, life forms, seasonal characteristics and application status of Ji’nan woody landscape plants, an investigation was conducted. Survey results showed that: there were a total of 535 species of Ji’nan City landscaping plant (including variants, subspecies and cultivars), belonged to 77 families and 199 genera, including 5 families 16 genera 49 species of gymnosperms, 72 families 183 genera and 486 species of angiosperms (containing dicotyledonous plants of 69 families, 174 genera and 467 species, monocotyledon plants of 3 families, 9 genera and 19 species). The number of Ji’nan woody landscape plants was very large. There were 286 kinds of plants trees, accounting for 53.4% of all species; 216 shrub species, accounting for 40.4% of all species; 33 kinds of vines, accounting for 6.2% of all species. Arbor and bush were widely used, however, lianas were lacked. And there were 103 evergreen species, accounting for 19.25% of all species, 432 deciduous trees species, accounting for 80.75% of all species. Application forms of woody plant in Ji’nan were diversified, but innovative applications were limited. Through the survey, we found that the use of Ji’nan woody plants had following problems: (1) the amount of landscape tree species in Ji’nan was large, but the utilization was not good, there was great room for improvement; (2) the application of evergreen species in Ji’nan was insufficient, the landscape is monotonous; (3) the application of native tree species was not enough. Suggestions based on the above problems were as follows: (1) scientific collocation must be carried out in city landscape greening plant selection; (2) the planting of native tree species should be extended; (3) introduction and domestication of tree varieties should be carried out actively. The survey provided a scientific basis for sustainable use of woody plants resources in Ji’nan.
