摘　　要：调查研究江西省17个天然毛竹林种群(Ⅲ度竹)的胸径、全株杆鲜重、全株枝叶鲜重、杆长、全杆节数、枝下节数、枝盘数、枝下高、叶长和叶宽、叶片长宽比、胸径处竹壁厚度、竹腔径、壁腔比、竹材含水率等表型特征。运用SPSS 13.0软件进行多元线性回归分析和偏相关分析,结果表明:全株秆鲜重、秆长、枝下节数、枝下高、胸径处壁厚、竹腔径呈现随经度而变化的地理模式,与纬度、海拔无关;胸径受经度和纬度的双重影响;枝盘数呈现随海拔而变化的地理模式。Seventeen natural PhyUostachys edulis populations were selected to study the phenotypic characteristics, including tree diameter at chest height, culm fresh weight, branch and leave fresh weight, culm length, the node number of the culm, node number of above culm, culm height, the length and width of the leave, the ratio between of the length and width of the leave, thickness of bamboo culm, diameter of bamboo cavity, the ratio between diameter of bamboo cavity and thickness of bamboo culm, moisture content of bamboo timber. The multiple linear regression and partial correlation were analyzed by SPSS13.0 software. The research indicated that, culm fresh weight, culm length, node number of above culm, tree diameter at chest height place wall thickness, the bamboo cavity diameter present the geography pattern which changes along with longitude, and it has nothing to do with latitude and devation; tree diameter at chest height is dually influenced by longitude and latitude, meanwhile the plate number presents the geography pattern which changes along with elevation.
