以江西省毛红椿天然林和人工林的冠幅、胸径调查数据为基础，拟合了冠幅（CW）与胸径（DBH）的相关关系，关系式为CW=1.1304+0.098315×DBH+0.000390×DBH2，并据此推算出不同经营目标下毛红椿的适宜经营密度、主伐年龄和造林密度。本研究为一定区域内毛红椿造林密度和合理经营密度的确定提供了一种理论依据，同时也为其他造林树种密度定量管理提供了借鉴。

Based on the investigation data such as crown width (CW) and diameter at breast height (DBH) of natural and artificial Toona ciliata var. pubescens forest in Jiangxi Province, the relationship formula between CW and DBH has be fitted as: CW=1.1304+0.098315 ×DBH+0.000390 ×DBH2, and suitable management density, principal felling age and planting density were given respectively of T. ciliata var. pubescens for various cultivation objectives. This research provides a theoretical basis for planting density and reasonable management density of T. ciliata var. pubescens forest in some specified region, as the same time, this provides reference for stand density quantitative management of the other afforestation tree species.
