The floristic composition, geographical composition and floristic characteristics of urban green space plants in Bishan district were analyzed. The results showed that angiosperm species were rich, accounting for more than 92.04% of the total species. The life form composition was dominated by woody plants; There were many single and small families, which were the main body of the flora; The genera were characterized by transition from tropics to temperate belt.
