Changwuyuan as a representative landform in the gully region of Loess Plateau was selected as thestudy area of this study.We analyzed canopy interception characteristics of apple trees and quantified canopyallocation of rainfall based on field observations during 45rainfall events.The results showed that throughfall

stemflow and canopy interception accounted for 75%～97%

0.2%～1.6%

and 2%～25%of the totalrainfall

respectively.The relationship between throughfall and total rainfall could be described roughly by aparabolic curve with upward opening and that between stemflow and total rainfall by a linear equation.Therelationship between canopy interception and total rainfall was cubic polynomial

which had the highest fitting degree with the observed values.
