Followed by a systematic analysis of the land area , forest area of ??accumulation , the accumulation of various advantages stand area , the accumulation of each age level stand area of each tree species accumulation , canopy density changes . Full return Forestry Bureau of Resource Protection strengthen awareness , unspoiled forest age group structure , forest area a variety of resources to lay the foundation of sustainable development , natural regeneration is better , forest ecological function better , the amount of annual forest growth as soon as possible to restore the forest laid the foundation , and to strengthen the management of forest resources ; adverse conditions : short vegetation period , the soil barren tree species in a single , stand and forest diameter class small . Divided into ecological forest by forest species dominant feature : water conservation forest, water and soil conservation forests , the revetment forest , road protection , nature reserve forest , the parent stand , environmental protection forests , scenic forest. Commercial forest is divided into fast growing forest the general timber stands .
