This study took Syringa oblata Lindl., which is most widely used in landscape greenery in Harbin, as an object of study and stressed on the environmental characteristics of Harbin City. The characteristics of postures, crown form, branch appearance and the leaf shape of Syringa oblata were analyzed by practical measurement of individual plant. Mathematic method and model were adopted to analyze the sample data and deeply explore the vegetation quantity of Syringa oblata in Harbin, and a quantitative method was put forward. It gets rid of the deficiency of greenery coverage in expression of ecological function of green plants and integrates green plants with their ecological function and ecological benefits, and can be extended to vegetation quantity study of other shrub species. This study can also provide scientific data and reference for match planting of green plants in different areas as well as the exertion of ecological function.
