A modified model of volume for stand density effect of Pinus massoniana plantation in Northern Fujian

The established modified model of volume for stand density effect in pinus massoniana plantation has such characteristics as variable power times, stronger adaptability and convenient application. The stand density effect of pinus massoniana plantation in northern Fujian Province was simulated by the modified matel, the results show that the modified model has beffer effect than those previous models, which provides the scientific basis for pinius masoniana's cultivation and density management.
