浙江省槭属植物区系与分布的初步研究

槭属Acer L.植物约有200种,广布于亚、欧及北美地区。我国有150种左右,各省区均有分布,浙江省有不少种类。本属有大量的用材树种和观赏树种。作者通过野外调查采集,结合查阅标本,并参考了近年来各地的调查结果,对该属在浙江的区系特点和分布规律进行了探讨,目的在于为保护和利用这一丰富的经济植物资源提供基础资料。

A PRELIMINARY STUDY OF THE FLORA AND DISTRIBUTION OF GENUS ACER IN ZHEJIANG PROVINCE

The floristic feature and geographical distribution of Acer in Zhejiang is described in the present paper. It is concluded that Zhejiang, especially the northwest mountains, is a refugium and an active differentiating regioa of Acer. The species in the province are mainly the endemic elements of China, others are the temperate Asian and the East Asian (Sino-Japanese) elements. Most of them belong to Southwest, Central, and East Chinese Floristics, distributed in the mountainous belt of the evergreen-deciduous broad-leaf mixed forest, the deciduous broad-leaf and the needle-broad-leaf mixed forest, a few belong to South Chinese Floristics, distributed in the mountainous evergreen broad-leaf forest belt in southeast and south area of the province. Finally, the original region of the genus is discussed. It's considered that the tropical to south subtropical Indo-Chinese region is the primitive original centre of the genus, Hengduan Mountains to Central China is the strongly active differentiating region of most of the deciduous sections and series.
