摘　　要：分别取用一元直线方程和一元幂函数方程对尾叶桉U6(E.urophylla U6)无性系立木木材的含水率与吸水率的关系进行研究、分析与探讨。分析结果表明:两个回归方程的结论一致,立木木材的含水率与吸水率两者呈负相关关系。经作检验含水率与吸水率的相关程度达高度紧密,相关显著性达极显著水平,精度可靠可供参考使用。研究中还发现:尾叶桉U6(E.urophylla U6)无性系立木生长在砖红壤,沉积沙壤和粗骨砖红壤的三个不同土壤类型上的立木木材的含水率的差异性均极显著;而生长在砖红壤上的立木与生长在沉积沙壤上的立木木材吸水率无显著差异,其余差异极显著。This paper studied the relationship between the water-contain rate and water absorption of stumpage of E urophylia clone u6 by means of one-dimensional linear equation and univariate power function equation. The result shows that the two equations draw the same conclusion, namely the moisture content rate and water absorption of stumpage is in negative correlation. The test shows that their relativeness reaches high degree up to extremely significant level. The accuracy is reliable and available for reference use. The study also discovers that the water- contain rate of the stumpage timber which grows on the latosol, sedimentary sand soil and coarse red soil differs greatly. Meanwhile the water absorption of stumpage timber which grows on the latosol and sedimentary sand soil shows no difference. Others show significant difference.
