| 摘 要： | 通过动态采集贵阳市春季21种植物新叶实景照片，用计算机程序语言R语言提取色彩数据，探讨其色彩变化规律以及客观表征的物候性，按照HSB色彩模式分析色彩属性随生长发育的变化规律。结果表明，春季不同植物叶色总体变化趋势为起初的红黄色随着生长发育转变为绿色；色彩属性变化特征，植物色彩的色相值随植物生长变化色相值增大，植物叶色饱和度值变化受到色相值的影响，色相值发生较大程度变化时，饱和度值呈下降趋势变化，植物色彩明度值随着生长的变化呈下降趋势；植物展叶期变色各时期长短关系为变色前期＜变色中期＜变色后期。研究结果将为贵阳市春季植物景观色彩规划设计提供合理建议。

| Abstract: | Pictures of the new leaves of 21 plant species occurring in in Guiyang in spring were taken and collected dynamically.The computer program language R was used to extract relative data of the leaf color,from which the change rules of the leaf color and the phenology of objective representation were discussed.HSB (hue,saturation,and brightness) color pattern was adopted to analyze the change rules of color attributes along with the growth and development of the plants.The results showed that the overall change trend of leaf color of different plants in spring was that the initial red-yellow color changed to green with the growth and development; the change characteristics of color attributes were that the color phase value of plant color increased with the growth of plants,and the change of leaf color saturation value was affected by the color phase value.When the color phase value changed to a greater extent,the saturation value showed a downward trend,while the plant color changed.The brightness value showed a downward trend with the change of growth,and the relationship between the length of each period of plant discoloration during leaf development was as follows:pre-discoloration stage
