| 摘 要： | 本文运用方差分析及统计假计检验对米槠（Ｃａｓｔａｎｏｐｓｉｓ ｃａｒｌｅｓｉｉ）、闽粤栲（Ｃ．ｆｉｓｓａ）及丝栗栲（Ｃ．ｆａｒｇｅｓｉｉ）三种小径阔叶树干容积密度变化规律的研究结果表明：树干不同高度容积密度之间差异不显著；树干各高度容积密度与树干容积密度之间的差异不显著，且以０．３Ｈ～０．４Ｈ之间的差异最小；树干各高度容积密度平均变动系数为６．４％；米槠与闽粤栲、丝栗栲与闽粤栲之间的树干容积密度差异显著，米槠与丝栗栲之间差异不显著；同一树种不同个体之间的容积密度变动系数为６．０％～７．８％．

| Abstract: | By means of variance analysis and test of statistical hypothessis,the author analysed the law of variation in the bulk density of small-diameter broad-leaf trunk of Castanopsis carlesii,C. fissa and C. far esii,with the resuIts showing that the variation of the bulk density of trunk at different height isn't remarkable,that the variation of bulk density between different heights and the whole trunk isn't remarkable,that it is the smallest in the height between O. 3H and O. 4H,that the variation of bulk density of trunk between C.carlessii and C. fissa,C. fargesii and C. fissa is remarkable, and that it is not remarkable between C. carlesii and C. fargesii. |
