【摘要】 木材变异性研究的最大困难在于研究对象庞大而复杂。缩小树种范围，加大力度，对最重要的树种进行材性径向变异模式的系统研究，是取得理论上较为完整、实用上较为有效的成果，将木材变异性研究提高到新水平的有效途径。更多还原

【Abstract】 The major difficulty in wood variation research is that the objective of the research is of too big size and great complexity. The research with limited range in tree species but greater intensity on the influencing factors is suggested an effective approach to obtain theoretically more abundant and practically more effective results, and a systematic study on wood radial variation patterns with most important afforestation tree species, taking as many influencing factors as possible is considered the relevant point.更多还原
