| 摘 要： | 在对嫩江沙地樟子松人工林生物量调查的基础上,采用回归分析的方法模拟了林龄与胸径、树高和生物量之间以及胸径、生物量与树高之间的数量关系,建立了樟子松林分各器官生物量回归方程,结果表明:林龄与胸径、树高和生物量相关紧密;采用W=aebD模型,地上生物量、树干、树枝、树根的回归方程的相关系数都达到了极显著水平,平均拟合率都大于70%。

| Abstract: | On the base of investigation of biomass of Pinus sylvestris var.mongolica plantation on sand land of Nenjiang River,taking the method of regression analysis,the quantitative relations of stand age with DBH,tree height with biomass,DBH,biomass with tree height were simulated,regression equations of biomass of organs of Pinus sylvestris var.mongolica stand were set up.Results showed that stand age with DBH,tree height with biomass have close correlations.Adopting model of W=ae~(bD),correlation coefficient of regression equation of biomass on the ground,bole,branch,under root reached extremely significant level.The mean fitting ratios are over 70%. |
