利用文献[1]中对树种的材色和地理分布的描述记载,采用分级数量化统计的方法,探讨了世界性大区域森林地理分布对木材材色的影响。其结果为:①木材树种群的材色受地理分布的影响。在地理分布因子中,纬度是主要的影响因子,经度因子对材色无显著影响;②纬度对树种群材色的影响作用表现为:低纬度区域的树种群深材色树种占百分比较大,浅材色树种较少。随着纬度的增加,浅材色树种逐渐减少,深材色树种逐渐增加;③针叶树材和阔叶树材树种群材色级别的分布特征有一定的区别。阔叶树材树种群中深材色树种所占有的百分比明显高于针叶树材树种群。
Based on the description of tree species’ color and geographical distribution in literature [1] and using the method of grading and quantification statistics, the effects of forest geography distribution on timber color in large-scale world regions are discussed. The results are as follows: (1) The wood color of timber tree is affected by the geographical distribution. Among the geographical distribution factors, latitude is the main influence factor, and longitude factor has no significant effect on the wood color. The effect of latitude on the color of tree species is as follows: the percentage of tree species in deep latitudes is larger, Shallow wood species less. With the increase of latitude, the number of shallow color species gradually decreased and the number of deep color species increased gradually. (3) There was a certain difference in the distribution characteristics of the color grade of coniferous tree and broadleaf tree species. The percentage of dark-colored species in broad-leaved tree species was significantly higher than that of coniferous tree species.
