摘　　要：测定了人工林毛白杨边心材的不同在色系统的色度学特征值．研究了毛白杨边村村色的株内变异情况。结果表明：毛白杨边材和心材及其不同板条的材色在XYZ空间（1964）、L*a*b*色空间（CIE1976）和孟塞尔色空间中．均有一定的分布范围．且不同板条的材色色度学参数在3个色空间中不完全相同。毛白杨边材材色株间存在显著差异。The color characteristics of sapwood and heartwood of Chinese white poplar in different color systemwere determined and the variation of color of sapwood among trees was also studied. The resultsshowed that the color characteristics of sapwood and heartwood all have their distribution range inXYZ, CIE L*a*b*(l976) and Munsell color system, and also vary among different sample panels. Thecolor of sapwood of Chinese white poplar among trees has significant difference.
