| 摘要： | 旨在研究张家口坝上地区不同无性繁殖造林小黑杨胸径-树高状况.以张家口坝上张北、沽源的无性繁殖造林小黑杨为研究对象,采用树干解析的方法获取插条、断根和埋桩造林小黑杨的胸径-树高实测数据,利用SPSS 18.0拟合3种无性繁殖造林小黑杨的胸径-树高模型.建立了插条造林小黑杨树高的Logistic方程模型,H=1/(0.1+0.559*0.724D),R2=0.992;断根造林小黑杨树高的Logistic方程模型幂函数模型,H=1/(0.1+0.617*0.766D),R2=0.988;埋桩造林小黑杨树高的幂函数模型,H=2.458*D0.524,R2=0.964.结果表明3种非线性回归模型的判定系数R2都大于0.96,D1.3能够很好地解释各器官树高. |
| 英文摘要： | This article is aimed at studying height & DBH conditions of Populus × Xiaohei which was afforested by different ways of clonal reproduction in Bashang area of Zhangjiakou City,and takes Populus ×Xiaohei which was afforested by clonal reproduction of Zhangbei County and Guyuan County as study object. Measured data were used of height & DBH( by ways of stem analysis) of Populus × Xiaohei which was afforested by cottage,mark- and- sweep and pile anchoring,and fitting was done for height & DBH models of Populu... |
