森林冠层对降雨的截留和再分配是生态水文学的重要研究内容.截留过程因降雨特征、森林类型及立地环境存在差异.以三峡库区山地的暖性针叶林、落叶阔叶林和针阔叶混交林三种林型为研究对象，对比了2018年植物生长季（4—11月）56场降雨的再分配特征及影响因素.结果表明：1)降雨在三种林型的再分配特征具有明显差异.暖性针叶林的透流量、树干径流量、林冠截留量分别占同期林外降雨的62.0%、7.2%、30.8%;落叶阔叶林分别占77.9%、3.5%、18.6%;针阔混交林分别占73.3%、2.7%、24%. 2)再分配参数与降雨量的相关分析显示，三种林型下树干茎流量、透流量均与降雨量呈线性正相关关系，冠层截留量与降雨量呈...

Rainfall interception and redistribution by forest canopy are important research contents of forest hydrology.The interception process varies due to meteorological conditions,forest types and site environment.Three forest types including warm coniferous forest,deciduous broad-leaved forest and coniferous and broad-leaved mixed forest in the Three Gorges Mountain Area were selected as experimental objects to compare the redistribution characteristics and influencing factors of 56 rainfall events in the 2018 plant growing season.The results are shown as follows.1)The redistribution characteristi...
