Abstract:

Based on forest resource inventory data in Saihanba Mechanized Forest Farm,forest resource quality,distribution pattern,and dynamic changes in forest area and volume were analyzed.The results showed from 1989 to 2017,both area and volume of forest resources in study area increased steadily. Saihanba obtained 6.1×104 hm2 and 7.52×106 m3 of the net increase in forest area and volume,respectively. The area proportions of young,mid-aged and near mature forests were almost equal,indicating age class structure was gradually reasonable. From the change of tree species structure,Larix principis-rupprechtii was in the dominant position,and the area propotion of Pinus sylvestris var.mongolica and Picea asperata also increased. Based on management problems of plantations and natural secondary forests in the study area,some measures and suggestions were presented.
