Accumulation effects of soil and water conservation function of artificial Chi nese pine forest system have been studied by methods of theory analysis a nd typical measurement. The results showed compared with bare-slope and bush-g rass catchement, the function that artificial Chinese pine forest system increas ed pure precipitation is evident,effects of artificial Chinese pine forest syst em to runoff time retarded is 2.5 and 4.3 times of bare-slope and bush-grass catchement, effects of artificial Chinese pine forest system to runoff kinetic increased is 25.0 an d 166.4 times of bare-slope and bush-grass catchement, effects of artificial Chinese pine forest system to capacities of runoff carried sediment increased i s 24.4 and 163.3 times of bare-slope and bush-grass catchement. Artificial Chi nese pine forest system can improved soil structure resulting in soil anti-scou rability and anti-erodibility, and its function made artificial Chines e pine forest system to take play a great role of soil and water conservation.
