摘　　要：为更加科学有效地防止城市内涝、有效进行雨水管理和园林水土保持,通过人工模拟降雨法和浸泡法,研究华东地区8种园林乔木冠层的降雨截留作用。结果表明,乔木冠层的截留能力与叶片特征、雨强、叶片重叠关系、降雨时间等有关,模式2、4时截留能力较好;平均叶面积对最大截留量影响最大,且为显著正相关;不同试验方法结果不同,西府海棠差异最小,灯台树差异最大,但浸泡法并不能反映最真实的降雨截留特征;单位面积最大截留量与最大截留率不呈比例关系。In order to prevent urban waterlogging more scientifically,implement rainwater management and soil and water conservation in gardens,the rainfall interception effect of 8 kinds of landscape trees canopy in North China was studied by artificial rainfall simulation and soaking method.The results show that the interception ability of tree canopy is related to leaf characteristics,rain intensity,leaf overlap relationship and rainfall time,and the interception ability is bet-ter in mode 2 and mode 4.The average leaf area has the greatest influence on the maximum interception,and the correla-tion is significant.The results of different experimental methods are different.The difference of Malus micromalus Maki-no is the smallest,and the difference of Bothrocaryum controversum is the largest,but soaking method can not reflect the most real characteristics of rainfall interception.The maximum interception per unit area is not proportional to the maxi-mum interception rate.
