摘要
对广西某林场1809个小班种植的速生桉人工林测得的资料进行拟合,分析了速生桉人工林生长方程的性质。运用SPSS软件的曲线回归拟合S型曲线,建立了速生桉人工林林分蓄积量生长模型。
The data from fast-growing eucalypts plantation with about 1809 sample plots in a forest farm of Guang＇xi was fitted, and the nature of the growth equation of fast-growing eucalypts plantation was ana- lyzed. By using the curve regression of SPSS to fit S curve, an accumulation growth model for fast-grow- ing eucalypts plantation was established.
