| 摘 要： | 在北京市区公园绿地种质资源调查的基础上,对其中8个公园绿地中常绿与落叶树种的比例进行比较分析。结果表明:8个公园绿地中常绿与落叶树种数量比例与投影面积由于公园特点的不同存在差异,但大部分数量比例分布在1∶1以下,均值为1∶3,投影面积总体比为1∶2;8个公园总体表现出落叶树种较多,而常绿树种较少的特点,群落季相变化比较明显。

| Abstract: | 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. |
