摘　　要：在充分分析黄菠萝天然林分布特征的基础上,对林分所处的立地级、形质指标和数量指标进行量化分级,将天然黄菠萝林分划分为3个等级。同时,以树高和胸径性状的数量指标与形质指标综合值将不同林分内的林木划分为3个林木级,并结合林木的结实状况,开展了天然黄菠萝优树选择标准的研究,旨在为该树种的遗传改良和创新利用奠定科学基础。Phellodendron amurense Rupr is not only one of the rare timber forests species but also an endangered species, the resource dry up and close to die out. The paper was on the basis of adequately analyze natural distribution characteristic of P. amurense, and classed to 3 grades for natural P. amurense forests basis on forest site level, index of morphological traits and quantitative indices. Moreover, trees were classed to 3 grades for different stand basis on the integrated value of index of morphological traits and quantitative indices of breast-height diameter and tree-height. we put up the study of selection criterion of natural P. amurense superior tree combine with fruit status of trees, aim to establish the science foundation of genetic improvement and innovation utilization for P. amurense.
