Comparative analysis of the ratio of evergreen to deciduous trees in green park space

We analyzed the ratio of evergreen to deciduous trees in eight urban parks based on the landscape plant resources survey of Beijing. The results show that the ratio and projected area ratio of evergreen to deciduous trees among the eight urban parks were different because of different characteristics of parks. But the ratio of evergreen to deciduous trees was mainly below 1∶1 with an average ratio of 1∶3, and the ratio of projected area was 1∶2, indicating that there are more deciduous trees than evergreen trees in urban parks, and the change of seasonal phase is obvious.
