| 摘 要： | 本文探讨了柳杉起源及变异,比较中国柳杉及日本柳杉形态特征,分析柳杉天然林生态环境及柳杉人工造林历史。通过分析,认为柳杉起源于中生代白垩纪的后期,或第三纪的始新世,天然分布中心在中国东南部——日本,形成间断的或孤立的分布区;柳杉远古时期广泛分布于北半球一带,后来由于气候变迁、地理分隔等因素,形成中国柳杉和日本柳杉两个种。

| Abstract: | This paper deals with the origin and variation of cryptomeria and makes a comparison of the characteristics of Cryptomeria fortunei and Cryptomeria japonica.Furthermore,an analysis is made of the ecological environment of the natural forest of cryptomeria and the history of its artificial forest.After the analysis,this paper holds that the cryptomeria originated from the late Mesozoic Cretaceous period,or the Tertiary Eocene,and its natural distribution centre was from southeast China to Japan,forming discontinuous or isolated distribution areas.Cryptomeria was widely distributed in the Northern Hemisphere in remote antiquity,then owing to the climate change,the geographical isolation or other factors,cryptomeria formed two sorts:Cryptomeria fortunei and Cryptomeria japonica. |
