Study on Canopy Interception Model and Its Parameter Characteristics of Pinus tabulaeformis Artificial Plantation in the Loess Plateau

YIN Zhun-sheng; SUN Chang-zhong; ZHAO Ming-yang

Based on the data deriving from 2008 to 2011 observed in the field, by using regression analysis, the relationship between rainfall and canopy interception of Pinus tabulaeformis plantation planted in the Loess Plateau was analyzed, and the regression parameters of the model were studied by the method of bootstrap. The results showed that both of the relationships could be analyzed by the nonlinear model I=aPb, which could be exactly expressed by I=0.584P0.576. This model not only had high fitting accuracy, but also the fitting parameters had good stability. The model could meet the requirement for significance, so it is feasible to be applied for the study areas.
