Diameter Distribution Yield Model of Pinus massoniana Plantation and Its Application

The system of diameter distribution yield model of Pinus massoniana plantation contained three parts:the stand factor model,the parameter recover model of Weibull distribution and the stand yield model.This model system not only ensured the compatibility among stand variables,but also realized the dynamic prediction of stand structure and yield,which offered technological means to evaluate the forest property and to confirm the forest economic maturity.
