摘　　要：测定了人工林杨树心、边材在不同表色系统中的色度学特征值,结果表明:人工林杨树木材材色指标,即CIE(1976)表色系统中明度L*、红绿色品指数a*、黄蓝色品指数b*和孟塞尔表色系统中明度V、色调值H及色饱和度值C在各表色系中均有一定的分布范围。对上述材色参数进行了相关性分析,研究了人工林杨树材色变异情况,结果表明杨树材色在无性系间存在显著的差异。The color characteristics of sapwood and heartwood from poplar plantation were determined according to different color systems. Results showed that the color characteristics of poplar wood all had their distribution ranges in CIE（1976） and Munsell color system. Correlations between different wood color parameters were analyzed, and the variation of the color characteristics of poplar wood was also studied. Results show that the wood colors of trees from different poplar clones have significant differences.
