Abstract
The basic theory and technology of the structure-based forest management is introduced and as a example, the application of the structure-based management in broadleaved Korean pine (Pinus koraiensis) stand is described, including data surveying, stand state characteristics analysis, management design and management evaluation. The analysis results by the structure-based forest management method show that the managed stands of broadleaved Korean pine forest is secondary forest; the management type is tending thinning and management urgency is urgent; the management direction is to improve forest health and climax species advantage extent. During this management operation, the climax species competitive potential was adjusted and 122 unhealthy trees were removed. The management evaluation results show that the management intensity is mild interference, the dominance of climax species and main associated species increased significantly, such as Pinus koraiensis, Abies holophylla, Phellodendron amurense, Tilia amurensis, Juglans mandshurica. The proportion of healthy trees in stand significantly increased so that the target of optimizing forest stand is achieved.
