摘    要:本文研究了中国产柳属植物的分布,并探讨了该属的起源与演化问题。  我国产柳     属植物255种,约占全世界总数的46%,隶属于37个组,几乎包括了该属所有的进化类型。     因此,中国是世界柳属植物种数最多、类型最丰富的地区。青藏高原的出现,是形成这一分布     特点的重要原因。我国柳属植物主要分布在西北、东北和西南地区。西北地区是中亚分布区     的一部分; 东北地区是东北亚分布区的一部分; 它们又都有一些中欧-西伯利亚和北极-高山成     分。青藏高原与其他分布区间的联系很少,是柳属又一个重要的分布中心。作为泛北极植物 区系的典型属之一的柳属,可能起源于东南亚热带山区。

关 键 词:柳属  地理分布

Abstract:The distribution of willows in China is studied in this paper.  The origin of this genus and its distribution in the world are also discussed.  There are 255 species of willows in China, taking up 46% of the total number of species of this genus in the world. They belong to 37 sections, which represent almost all forms.  China is therefore the richest area in species and sections of willows in the world. This is mostly caused by the uplifting of Qinghai-Xizang (Tibet) plateau.  The willows in China are mainly distributed in north- western, northeastern and southwestern regions. The northwest is a part of central Asian flora. The northeast is a part of northeastern Asian flora.  They both have some of the Europe-Sibe- ria and Arctic-Alpine elements.  Qinghai-Xizang plateau is  another important  distribution center of willows, which has no close relation with other floristic regions.  As one of typical genera of the Holarctic flora, Salix has probably originated in the tropical mountains of Southeast Asia.
