This paper has investigated and studied the plant species of green land in Xiaolan Town,Zhongshan City.According to the survey,garden plants in Xiaolan town are abundant and varied including 105 families and 433 species,most of which are planted in parks and nurseries.In contrast,there are much fewer street trees and road trees.Arbors and shrubberies are widely cultivated,especially efflorescent arbors are extensively planted in parks,while lianas are rarely used.Aspect and type of the artificial forest are very monotonous.There is a serious lack of green land in the old urban area.Some factories and schools do not attach importance to greening.The author points out that garden trees should be reasonably chosen,and indigenes mainly planted,such as Magnoliaceae,and in the meantime exotic species introduced,such as Bignonaceae,Bombacaceae and Fabales.The residual forest of Eucalyptus and Acacia in Yuanlan Hill should be improved by building the mingled forest,in which main trees selected from Lauraceae,Fagaceae and Theaceae will be planted together by stages and in batches.In the end,garden plants suitable for different types of green land are picked out.
