摘要: 旨在研究张家口坝上地区不同无性繁殖造林小黑杨生物量状况,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,采用树干解析和收割的方法获取插条、断根和埋桩造林的小黑杨的生物量实测数据,利用SPSS18.0拟合3种无性繁殖造林小黑杨的生物量模型,其结果表明:(1)非线性回归模型的判定系数R2都大于0.96,D1.3和D1.32H能够很好解释各器官生物量.(2)分别建立了插条造林小黑杨生物量的Logistic方程模型、断根造林小黑杨生物量的幂函数模型和埋桩造林小黑杨生物量的Logistic方程模型.
英文摘要: In order to investigate the biomass state of Populus×xiaohei which was afforested by different ways of asexual reproduction in Bashang region of Zhangjiakou city, by taking Populus×xiaohei plantation afforested by asexual reproduction in Zhangbei county and Guyuan county as study objects, the biomass data of Populus×xiaohei were measured by stem analysis and harvesting methods, which were afforested by cuttage, mark-and-sweep and pile anchoring, and the biomass models of Populus×xiaohei afforested by the th...
