Abstract: Honghuaerji Forestry Administration is the centralized distribution area of our country's natural Pinus sylvestris (Pinus sylvestris var.Mongolica).Pinus sylvestris accounts for 52 percent of the forest land,The proportion of Birch (Betula platyphylla) stands at 46 percent.Evaluating the ecological functions of the forestry administration,in order to develop sound forest management plan,provide a theoretical basis for guiding forest management.According to forest resources planning and design data in Honghuaerji,national continuous forest inventory assessment methods are used to evaluate the ecological functions of the forestry administration.The results showed that the forest eco-functional level in Honghuaerji is mainly at medium level,occupying a forest area about 93%;eco-functional levels for the good and bad ratings of the forest area are 4% and 3%;global forest ecological function index is 0.55,and the forest eco-functional level is “medium”.In accordance with the evaluation of each forest farm (nature reserve),the best ecological function of the forest is Honghuaerji Nature Reserve,and the worst is Baritu.According to each age group evaluation,the worst ecological function is in young stand forests,ecological functions of the remaining age groups were better than the average.According to species structure evaluation,the ecological function of deciduous broad-leaved forest,deciduous broad-leaved and coniferous forest,and broad-leaved mixed forest are better than pure coniferous forest,pure broad-leaved forest and relatively-pure coniferous forest.According to species origin evaluation,the ecological function of natural forest is better than plantation.
