Abstract：The evaluation of bamboo ornamental value usually requires evaluators with strong expertise, but the higher level of subjectivity and random in the valuation process often leads to artificial difference due to the different evaluators carrying out the evaluation and makes hard to unify the results. Based on the ecological characteristics of singular ornamental bamboo, this paper evaluated the ornamental value of singular ornamental bamboo by percentile method. The quantitative method and classification standard for ornamental value of singular ornamental bamboo were presented, with which 42 species of singular ornamental bamboo including Phyllostachys edulis cv. Tao kiang were evaluated at the Bamboo Species Orchard in Jiangxi Academy of Forestry. This study is aimed at providing the basis for the bamboo's ornamental value evaluation, which is of important realistic significance to promote the protection and development of singular ornamental bamboo.
