- Abstract
Based on the 2005-2008 observation data of canopy interception in larch plantation in eastern Liaoning Province, and by using Gash model, the interception process was simulated. In the plantation, there was a significant positive correlation between throughfall and rainfall ( R² = 0. 98) , and the annual throughfall accounted for 77. 64% of the total rainfall. The canopy interception was positively correlated with rainfall and its intensity. The canopy interception simulated by Gash model was lower than the measured values, except for the results in 2007 because of the short intervals between rainfalls. The absolute error of simulated values had a negative exponential correlation with rainfall, and the range was 1. 26% -68. 96% , and the mean value was 29. 09%. The estimated values were almost equal to the measured values, with the correlation coefficient being 0. 91.
