The results were as follows: in the levels of criterion, ecological function was the most important, followed by aesthetic function, service function. And in the levels of index, the top three were the diversity of life forms, the coordination and symbiosis between plants, and the variation of colors and seasonal aspects. The results of evaluation showed that there were ten plant landscape units at the level of I, accounting for 33.3% of the total units that were evaluated, eighteen units at the level of Ⅱ, accounting for 60% of the total, two units at the level of Ⅲ, accounting for 6.7% of the total, and the number of units at the level of Ⅳ was zero.
