Research on the Structure of Paulownia elongata Stand

The research on the structure of Paulownia elongata stand indicates that the first branching height is positively relative to the site index and seedling quality, but negatively to the second branching height. The height variation of different diameter classes in P. elongata stands with sites and ages can be simulated by established H-curve function. In the prediction of the diameter structure of P. elongata stand, this paper reveals that L PRM is better than PRM(Weibull).
