From June to Sepetember 2009,a typical shrub,Caragana microphlla,commonly used to stabilise sand dunes,was selected from Horqin Sandy Land to investigate rainfall redistribution.During the entire experiment,the cumulative amount of rainfall was 103.1mm.The amount of throughfall(TF)was 73.1mm (70.9% of the total rainfall),of stemflow(SF)was 4.1mm (4.0%),and of interception(I) was 25.8mm (25.1%).Regression analysis showed a significant positive linear correlation between rainfall and TF,SF,and I.The correlation between rainfall and TF% is well represented by an exponential function as is I%.Furthermore,TF% was an exponential function of the rain intensity in 1hour(Ih),but for I% was a power function of Ihin this experiment.
