摘 要：以五种桉树人工林木材为研究材料，用测色仪和氙衰减仪测试了五种桉树木材的颜色和耐光性，比较了这些桉树木材的颜色参数，结果表明：不同种类桉树木材材色参数之间差异显著，桉木心材部分的色品指数和色饱和度高于边材；桉木的耐光性随氙灯照射时间的增加而逐渐变差。

With unit integrating and scale conversion, the transpirations determined by lysimeter and L I21600 stoma mete r are analyzed wit h Variance Analysis Method. The results s how that the difference between species is significant (P.05), but t he difference between methods is not significant. It indicates t hat t he scale conversion between leaf level and plant population level based on canopy and leaf area index is successful.

通过单位换算统一和尺度转换，蒸渗池和LI1600气孔计测定结果进行方差分析，表明物种间差异达显著水平(P.05)，测定方法间(蒸渗池和LI1600气孔计)差异不显著；从而说明本研究以叶面积指数和植物冠层盖度为基础，进行叶片水平与种群水平间的尺度转换是可行的。
