The near natural sustainable forest management

The basic idea of near natural forest management is to cultivate a near natural forest. The management objective is to constantly give play of the multiple functions of forest. The basic methods and issues are single plant operation and natural update. The reference object is the natural forest that has similar site condition and high natural degree. The reference species are the major and minor species in the tree layer of the natural forest. The target tree density is determined according to the existing stand structure and growth condition of trees. "Profit maximization"is the principle of determining the target diameter. The crown canopy will be gradually dispersed,special target trees will be replanted,thus the artificial forest will steadily enter the natural update program.
