摘要
作者认为狗枣子 (Actinidiakolomikta (Maxim .&Rupr.)Maxim .)是一个多型的、具有两个间断布区的适应于地带性针阔叶混交林生境的猕猴桃属植物。文中还根据狗枣子的生态地理分布特征 ,认为狗枣子的现代中国西南 - -东北亚间断分布的格局是东亚第三纪以来气候回旋变化的结果所造成的。狗枣子原始分布区 (中国西南高山 )受气候回旋变化的胁迫衍生出次生的东北亚分布区。由于气候的振荡变化 ,水平方向上原有的连续分布区逐渐断裂而形成现代的间断分布格局。据此文中还指出 。
The polymorphic species Actinidia kolomikta (Maxim. & Rupr.) Maxim., which with two discontinuous areas, is inherently sensitive to local changes in habitat and it strictly grows in Mixed Coniferous and Broadleaved Forest environments either in low altitudes of North-east Asia or in high altitudes of South-west China. According to its eco-geographical distribution and its affnities, it was pointed out that this species might be considered to have originated in high altitudes of Southwest China. The formation of its typical North-eastern Asia and South-west China discontinuous distribution pattern has been made by the driving force of the episodically environmental changes in Quaternary. And, in this paper the author has disscused the phytogeographic significances of its present distributional pattern.
