Artificial timber forest dominated by pine and fir can cause loss of water and soil, decrease of forestland productivity and protection function , and easy occurrence of pests and diseases. The managemental pattern of timber forest dominated by sub-nataral forest includes the measures as follows:①breeding timber forest by natural regenation ability; ②Changing clearing cutting into selective cutting ;③ breeding uneven-aged forest. This pattern could decrease expenditure of forest breeding, remain the stability of forest ecosystem and realize aim of forestry sustanible development.
