Plant structure and architecture have a significant influence on how people interpret them. Bamboo plants have highly ornamental attributes, but the traits that attract people the most are still unknown. Therefore, to assess the people's preference for ornamental features of bamboo plants, eye-tracking measures (fixation count, percent of dwell time, pupil size, and saccade amplitude) and a questionnaire survey about subjective preference were conducted by ninety college students as the participants. The result showed that subjective ratings of stem color, leaf stripes, and stem stripes showed a significant positive correlation with the fixation count. The pupil size and saccade amplitude of different ornamental features were not correlated with the subjective ratings. According to random forest model, fixation count was the most influential aspect affecting subjective ratings. Based on integrated eye-tracking measures and subjective ratings, we conclude that people prefer the ornamental features like green stem, green stem with irregular yellow stripes or yellow stem with narrow green stripes, leaves with less number of stripes, normal stem, and tree. In addition, people prefer natural traits, for instance, green stem, normal stem, and tree, related to latent conscious belief and evolutionary adaptation. Abnormal traits, such as leaf stripes and stem stripes attract people’s visual attention and interests, making the fixation count and increasing the percentage of dwell time. This study has significant implications for landscape experts in the design and maintenance of ornamental bamboo plantations in China as well as in other areas of the world.

植物的结构和体系结构对人们如何解释它们具有重大影响。竹子植物具有很高的观赏性，但是吸引人最多的特征仍是未知的。因此，为评估人们对竹类植物装饰特性的偏爱，对90名大学生进行了眼动追踪措施（注视次数，停留时间百分比，瞳孔大小和扫视幅度）以及关于主观偏爱的问卷调查。 。结果表明，茎颜色，叶条纹和茎条纹的主观评价与固色数呈显着正相关。不同装饰特征的瞳孔大小和扫视幅度与主观等级无关。根据随机森林模型，注视次数是影响主观评分的最有影响力的方面。基于综合的眼动追踪方法和主观评分，我们得出结论，人们偏爱装饰性特征，例如绿色茎，带有不规则黄色条纹的绿色茎或带有绿色条纹的黄色茎，条纹数量少的叶子，正常茎和树。此外，人们更喜欢与潜在潜意识信念和进化适应有关的自然特征，例如绿色茎，正常茎和树木。叶条纹和茎条纹等异常特征吸引了人们的视觉注意力和兴趣，使注视次数增加并延长了停留时间的百分比。
