Litter Interception Simulation of Pinus tabulaeformis Plantation on Loess Plateau

  • Received Date: 2014-03-24
  • In order to establish the proper model of the litter interception, based on the data deriving from 2008 to 2011, by using regression analysis, the relationship between rainfall (throughfall) and litter interception of Pinus tabulaeformis plantation on the semi-arid Loess Plateau was analyzed, and the regression parameters of the model were determined by Bootstrap. The results showed that both throughfall and litter interception could be analyzed by the nonlinear model Ic=aPb, which could be exactly presented as Ic=0.499P0.627 and Ic=0.717TF0.513. This model has high fitting accuracy, and the fitting parameters have good stability. The model could meet the requirement for significance.

Abstract: In order to establish the proper model of the litter interception, based on the data deriving from 2008 to 2011, by using regression analysis, the relationship between rainfall (throughfall) and litter interception of Pinus tabulaeformis plantation on the semi-arid Loess Plateau was analyzed, and the regression parameters of the model were determined by Bootstrap. The results showed that both throughfall and litter interception could be analyzed by the nonlinear model Ic=aPb, which could be exactly presented as Ic=0.499P0.627 and Ic=0.717TF0.513. This model has high fitting accuracy, and the fitting parameters have good stability. The model could meet the requirement for significance.
