Through field survey and typical sample-plot method,plant landscape of Qianjiang New Town CBD in Hangzhou park was investigated,and plant diversity and community structure were analyzed. The result showed that there were 108 plant species under 60 families and 85 genera in this CBD park. Plant richness was relatively high and plant landscape was diversity. The species proportion of tree,shrub and herb was reasonable,and the propotion was also reasonable between evergreen trees and deciduous trees,between evergreen tree and deciduous shrubs. The structure of plant community,which was dominated by mixed type and multiple layer,was classified into 3 types,namely the deciduous broad-leaved forest,evergreen broad-leaved forest,and mixed forest of evergreen and deciduous broad-leaved,and it was characterised by seasonal landscape and ecological feature. Different types of green plant spaces,namely positively accessable type,negatively accessible type and un-accessible type,accounted for 22. 2 %,16. 7 %,and 61. 1 % respectively. For city parks,however,accessible type is more important than un-accessible type,and the portion of accessible type should be increased to meet the need of population agglomeration in Hangzhou CBD park.
