通过研究马尾松林分胸径与冠幅之间的相关规律，编制了林分适宜密度表。在此基础上通过对胸径连年生长量的变化规律、胸径生长过程、林分平均胸径与间伐木平均胸径、间伐木平均胸径与间伐木平均树高之间相关关系的研究，从中选择出最佳的相关关系式，并据此确定马尾松中幼林抚育间伐的起始期、间隔期、间伐强度、间伐蓄积量，为科学合理地进行抚育间伐、选择造林密度及提供营林设计和调查规划参考数据服务。
By studying the relationship between DBH and crown width of Pinus massoniana, a suitable density table of forest stands was compiled. On the basis of this study, the relationship between the annual growth of DBH and the growth of DBH, the average DBH of stands and the average DBH of inter-cuttings, the average DBH of inter-cuttings and the average height of inter-cuttings were selected. And then determine the initial period, interval time, thinning intensity and thinning stock volume of young tree stand of young masson pine in order to scientifically and reasonably thin out the deforestation, select the planting density, and provide reference service of forest design and survey planning .
