Comparison of Tree Species Diversity of Varied Plant Communities in Some Parks in Kunming City

The four major reasons leading to the low tree species diversity of man-made plant communities in parks of Kunming City were analyzed based on investigating into the tree species diversities of varied types of plant communities of some parks in the city. Accordingly, five approaches to increase the tree species diversity of artificial plant communities were put forward that would be helpful to plant design for the parks and gardens in Kinming City.
