渭北黄土高原刺槐林分蓄积收获量表的编制

Volume Yield Table of Robinia pseudoacacia Stands on Weibei Loess Plateau

将现实林分每公顷断面积、蓄积量转换成标准林分每公顷断面积、蓄积量。然后采用幂函数式建立了林分平均直径、林分平均高、林分每公顷断面积、林分每公顷伐前与伐后蓄积生长模型，编制了刺槐林分蓄积收获量表。模型的相关系数大于０．９８１，相对系统误差小于±２．６１１％，相对均方差小于１０．２０％。此表可在生产实践中应用。

Cross section area and volume perhectare of the real stand were changed to those of standard stand to establish growth models of D, H, G, M, Mc and to draw up the volume yield table of Robinia pseudoacao stand. Relative coefficients of the models were over 0 981.Relative systematic errors were below ±2.612%. Relative mean variances were below 10 20%.The table can be applied in forest management.
