摘　　要：园林植物是预防水土流失的重要措施之一,而树冠截留雨水效果则是筛选园林植物的核心指标。通过对成都市园林植物树冠截留雨水效果的实验分析,得出以下结论:植物的枝叶疏密度越高,树叶空隙就越小,有效降低穿透雨量,提高树冠截留效果;将树冠修剪成球状,可以增大采光面积,促进植物的整体增长,提高枝叶疏密度;群植模式能够促进各植物之间的枝叶交叉,有利于枝叶疏密度的提升。降雨量和降雨强度影响到树冠截留,园林种植应尽量选择枝叶疏密度高的植物,如罗汉松、黄葛树等。Landscape plants are one of the important measures to prevent soil erosion, and the effect of rainwater interception by canopy is the core index to screen landscape plants.Through the experimental analysis of rainwater interception effect of garden plant crown in Chengdu, the following conclusions are drawn: the higher the sparse density of plant branches and leaves, the smaller the leaf gap, effectively reducing the penetrating rainfall and improving the effect of tree crown interception;pruning the crown into spherical shape can increase the lighting area, promote the overall growth of plants, and improve the sparse density of branches and leaves;The intersection of branches and leaves is beneficial to the increase of sparse density of branches and leaves.Rainfall and rainfall intensity affect canopy interception.Garden planting should try to select plants with high density of branches and leaves, such as Podocarpus grosvenorii and Pueraria lobata.
