| 摘 要： | 许多学者先后对东北林区桦木属的分类进行了深入研究,对种及种下分类等级意见至今不一致,给综合开发利用桦木类群资源造成了混乱。笔者经多年深入林区实践、调查、采集标本,结合种群特征、地理分布、生境特点综合分类,不以蜡叶标本作为唯一依据,鉴定了桦木属种及种下等级,基本上同意傅沛云(1995)对东北林区桦木属的分类。但笔者认为东北白桦(B.mandshurica(Regel) Nakai)应视为独立种,取消栓皮白桦(Betula platyphylla Suk.var. phellodendroides Tung)名称及英吉里岳桦(ermanii Cham.var.yingkiliensis liou et Wang)名称,卵叶桦(Betula ovalifolia Rupr )不应该降为柴桦变种(Betula fruticosa Pall.),仍为独立种。图1表4参10。

| Abstract: | Many researches have been carried out on the taxonomy ofBetula in northeast of China, but the classification of species and subdivision of species had some divergences at all times, which led to a disorder for developing and utilizing resources ofBetula. In this paper, species and subdivision ofBetula were classified not only according to the wax sample ofBetula but also the comprehensive taxonomy of population characters, geographical distribution, and the habitat. The conclusion supported the Fu Pei-yuns’ (1995) viewpoint of the taxonomy ofBetula in the northeast of China. ButB. mandshurica (Regel) Nakai should be considered as one single species, the name ofB. platyphyla Suk. varphellodendroides Tung should be the synonym ofB. platyphyla varplatyphyla, andB. ermanii Cham. var.yingkiliensis liou et Wang should be incorporated intoB. ermanii Cham.B. ovalifolia Rupr should not be regarded as a variety ofB. fruticosa Pall. but as one single species. |
