Abstract: Interception amount and intercepting processes of artificial Chinese pine litter were studied by local measure methods.The results showed the interception amount of litter and its interception rate were 49.3mm and 12.5% respectively.The interception processes of litter were affected by rainfall and environmental factors and also related with litter dry conditions.Interception processes of litter increased quickly when rainfall began,the increasing of amount interception varied slightly when rainfall went on to a certain period of time,after rainfall reached the peak value,the interception amount fluctuated at this point.The interception processes can be described using combination of line and sin function and the sin function can deal with the effects of biology and environment on litter absorption processes.The model has extensive utilization in forest hydrology and soil and water conservation evaluation.

Key words: Loess Plateau, artificial Chinese pine forest, litter interception, dynamic processes
