| 【目的】研究广州市园林绿化常用的 6 种灌木植物冠层截留特征，为灌木植物在海绵城市建设中的
应用提供参考依据。【方法】采用浸泡法测量大红花（Hibiscus rosa-sinensis）、勒杜鹃（Bougainvillea glabra）、
红 花 檵 木（Loropetalum chinense var. rubrum）、 海 桐（Pittosporum tobira）、 米 仔 兰（Aglaia odorata）、
灰莉（Fagraea ceilanica）叶片最大截留量、单位叶面积最大截留量、枝条最大截留量、冠层最大截留量等指标。
【结果】6 种园林灌木植物叶片最大截留量在 41.20~209.73 mg 之间，单位叶面积最大截留量在 6.84~15.80 mg/
cm2 之间，枝条最大截留量在 1.85~14.85 g 之间，冠层最大截留量在 406.49~3 204.04 g/m2 之间。6 种园林灌木植
物中，红花檵木单位叶面积截留量最大，簕杜鹃叶片截留量最高，灰莉叶片持水性能最好，大红花枝条截留量
和冠层截留量最大。 6 种园林灌木植物叶片最大截留量与叶面积呈极显著正相关，冠层最大截留量与枝条最大截
留量呈极显著正相关。【结论】在海绵城市建设中，可选用大红花等冠层截留量大及灰莉等持水性能好的园林
灌木植物进行城市绿化，缓解城市用水压力，促进广州市生态可持续发展。 |

| 【Objective】Canopy interception characteristics of six shrub plants used for landscaping in Guangzhou
were studied in order to provide references for the application of shrub plants in the construction of sponge city.
【Method】The maximum interception of leaves, the maximum interception of unit leaf area, the maximum interception
of branch, and the maximum interception of canopy of Hibiscus rosa-sinensis, Bougainvillea glabra, Loropetalum
chinense var. rubrum, Pittosporum tobira, Aglaia odorata and Fagraea ceilanica were measured by submerging method.
【Result】The maximum interception of leaves of 6 landscape shrub plants was between 41.20-209.73 mg. The maximum
interception of unit leaf area of 6 landscape shrub plants was between 6.84-15.80 mg/cm2
. The maximum interception of
branch of 6 landscape shrub plants was between 1.85-14.85 g. The maximum interception of canopy of 6 landscape shrub
plants was between 406.49-3 204.04 g/m2
. The interception of unit leaf area of L. chinense var. rubrum was the largest
among 6 landscape shrub plants. The interception of leaves of B. glabra was the highest among 6 landscape shrub plants.
F. ceilanica was the best one in blade water holding performance among 6 landscape shrub plants. Among the 6 landscape shrub plants, H. rosa-sinensis had the maximum interception of branch and the maximum interception of canopy. The
maximum interception of leaves had a significantly positive correlation with leaf area in 6 landscape shrub plants. The maximum
interception of canopy had a significantly positive correlation with maximum interception of branch in 6 landscape shrub plants.
【Conclusion】Some landscape shrub plants with high canopy interception such as H. rosa-sinensis and some landscape
shrub plants with high water holding performance such as F. ceilanica can be used in construction of sponge city to relieve the
pressure of city water consumption and improve the ecological and sustainable development of Guangzhou City. |
