338 species of plants have been used on the green space of Foshan urban district,including varieties and cultivars,which are subdivided into 215 genera and 86 families.And there were 177 species of trees among them,which are subdivided into 111 genera and 47 families.The 5 families of most trees were Moraceae;Palmaceae;Myrtaeae;Caesalpininaeae and Papilionaceae.There was significant difference in plant species diversity of different districts of urban green space.The plant species diversity in Chancheng district was greater than that of Shiwan district.There were also obvious differences in plant species diversity among different types of green space.The plant species diversity on open green space was greater than that of other types.The major trees used on urban green space were evergreen trees,native trees or slowly growing trees.The trees used commonly on Foshan urban green space were 30 species of plants or trees.The plant species diversity of main urban green space was bad.How do we build and protect plant species and tree diversity on urban green space are also discussed in this paper.
