【Abstract】 Based on the research achievements of the past decade, by combining cultivation principles with cultivation experiences as methodology, and aimed at guiding silviculture practices effectively, the silviculture model micro computer has been developed for industrial plantations of southern type poplars. The system includes systematic research on the modelling principle, the structure and function of the system, and the introduction of developing techniques and the methods. The established model can deal with site quality evolution, silviculture modelling, and the economic benefits evolution. The results show that this model system has the characteristics of high precision, good practicality and rationality. Therefore it can supply silviculturists with a guiding tool to use in intensive oriented cultivation for industrial plantations of southern type poplars, and it may open up a broad prospect for its application in the future.更多还原
