Abstract: Through statistical analysis of forest resources inventory and planning data for Dangchuan Forest farm in Xiaolongshan forest area,this paper aimed to expound the non-commercial forest characteristics and classify management types according to the origin of the forest,tree species (groups),site types and management objectives.The results showed natural forest was in the majority,the forest category structure was relatively simple,it was mainly the water source conservation forest,especially the Pinus armandii,Quercus spp.,Betula albosinensis,Betula platyphylla forests,etc.The volume of per unit area for mixed forest was significantly higher than pure coniferous forest and pure broad-leaved forest.Forest age structure is unreasonable,middle-aged forest and nearmature forest were dominant.Four site types,such as middle geomorphology & shady slope & thinner soil layer & steep slope,had bigger volume and area proportion of non-commercial forests.2 430 subcompartments of non-commercial forest can be divided into 29 management types.This will provide theoretical basis and practical guidance to form complete management measures for non-commercial forest in Xiaolongshan.

Key words: Xiaolongshan, non-commercial forest, management type
