摘  要:在收取编制尾叶桉U6(E.urophylla u6)立木二元材积表数据和资料的同时,收集尾叶桉U6立木胶合板材(又称旋切板材)出材量数据与资料,在收取的1059株有效样木中取胸径7.0~18.9cm的886株样木的胶合板材的出材量数据用作编制尾叶桉U6立木胶合板材出材量表,经作检验精度可靠,高达99.54%,达一级精度;胸径与树高、胸径与出材量,树高与出材量的简相关系数分别为:r_(D-H)=0.986417,r_(D-V)=0.996893,r_(H-V)=0.972275;出材量与胸径与树高的复相关系数为:R_(V-D-H)=0.999166。胸径与树高、胸径与出材量,树高与出材量的简相关系数和出材量与胸径与树高的复相关系数均达极紧密程度,回归效果呈高度显著水平,F值为:F=26358.0**>F_(2.883)^(0.01)=4.64。故回归方程:V_(胶合板材)=4.096632×10^(-3)D^(2.098099)H^(-0.992394)在该林区适用。In collecting data and compiling binary volume table ofE. urophylla u6, the data and information of plywood (namely rotary cutting wood) were collected as well. The plywood amount table of E. urophylla u6 was compiled with 886 sample trees whose breast-height diameter ranged 7.0-18.9cm among the valid 1059 sample trees. The accuracy was tested as reliable, amount to class one 99.54%;the simple correlation coefficient of breast-height diameter to tree height, breast-height diameter to volume, tree height to volume was respectively as rD-H=0.986417,rD-V=0.996893,rH-V=0.972275.The complex correlation coefficient of volume to breast-height diameter and tree height was RV-D-H=0.999166. Both the simple correlation coefficient and the complex correlation coefficient reached extremely close degree. The regression effect was remarkable with F=26358.0**〉F0.012.883=4.64. Therefore regression equation Vplywood=4.096632×10^-3D^2.098099H^-0.992394 is suitable for this area.
