Abstract

In order to develop and use Pinus massoniana better and provide reference basis for its operation and management,the multi-model selection were used to analyze and discuss the individual tree diameter growth progress of Pinus massoniana Lamb in Shibao town,Chongqing City. Results showed that whether it was a dominant tree or oppressed tree,Richards function was the best to fit the diameter of the growth process of P. massoniana,better than Schumacher function,while Gauss function was the worst. However,the parameters of the Richards function were too much,and the amount of diameter growth of P. massoniana estimated by Richards function did not meet the actual growth conditions,therefore,Schumacher function was the best model which could be used to describe the diameter growth process of Pinus massoniana Lamb in Shibao town,Chongqing Province.
