The results were as follows: 1 There were 7 133 trees, belonging to 23 species and 18 genera and 13 families, and their average DBH, crown and height were respectively 27.59 cm, 4.10 m and 6.94 m. In general their average crown was relative small. 2 S, H (Shannon-Wiener index), and D of biodiversity index were small, and there were the obvious difference in those indexes among different streets, which suggested that there were certain monotone of the tree species and structure layer. 3 The dominant species mainly consisted of evergreen trees that were Ficus virens var. sublanveolata, Ficus benjamina, Roystonea regia, Terminalia hainanensis, T.
