Based on the construction of urban landscape forest and application of stereoscopic landscapes in CAST(Chongqing Academy of Science and Technology),Ginkgo biloba L.,Ficus virens Ait.var.sublanceolata(Miq.) Corner,Cinnamomum camphora and Magnolia liliflora were selected as major tree species and stereoscopic landscaping plants for the "CAST Stereoscopic Landscape Demonstration Project".Through investigating landscapes and functions of all these species in the urban landscaping,the authors anaiyzed stereoscopic plant landscapes of the CAST project,summarized application of these tree species in the stereoscopic landscapes,and concluded representativeness of these species in the CAST project.Finally,deficiencies of tree species in the CAST project,their maintenance and management were analyzed to ensure the reasonable application of tree species,and to provide references for the construction of urban landscape forest and popularization of stereoscopic landscapes.
