西伯利亚红松(Pinus sibirica Du Tour)在大兴安岭的存在

1981年以来赵光仪等以营养器官形态解剖特征，结合生态地理分析，连续报道了西伯利亚红松 Pinus sibirica在大兴安岭的存在，引起争议。1989年秋，我们于大兴安岭满归林业局采到了争议松树的球果，经同主产区的西伯利亚红松及红松P．koraiensis标本对照研究，再次认定大兴安岭争议松树确属西伯利亚红松。从而最终证实了吴中伦先生25年前关于西伯利亚红松存在于大兴安岭的预见，纠正了所谓“漠河红松”30余年的误称。根据10年来调查研究结果绘出了大兴安岭及其毗邻地区红松、西伯利亚红松分布略图，显示了两种松树生态地理学特征的深刻差异。

Occurrence of Pinus sibirica Du Tour in Da Hinggan Mountains

 Based on the morphological and anatomical characteristics of vegetative or- gans,as well as the ecology and geography, Zhao Guang-yi et al. have reported the occurrence of siberian pine(Pinus sibirica) in the Da Hinggan Mountains continuously since 1981, that arouses disputing, The pine cones of the disputing pine were collected in the Mangui Forestry Bureau in the Da Hinggan Mountains, Northeast China, in autumn of 1989. By comparing it with those of Pinus sibirica and P. koraiensis it is proved that the disputing pine in the Da Hinggan Mountains is P. sibirica, but not P. koraiensis. And the 30-year old wrong name of “Mohe Korean Pine” has been corrected. A map showing the distribution of the P. koraiensis and P. sibirica in the DaHinggan Mountains and its adjacent regionswas drawn according to the 10-year investigation.
