摘要:

    本文用数值分类的关联分析方法对国产荚蒾属 Viburnum  所有72种的分布式样进行
    了研究,旨在为中国植物区系分区的工作提供若干依据。中国荚蒾属的遗传变异中心是在中
    南部而不在南部或西南部的事实强烈地暗示这是一个亚热带性质的属。  四川西南部是西部
    特有成分最密集的地区。尽管横断山脉地区地形复杂,但那里只有几种荚蒾属植物。台湾的
    种主要是亚热带性质的,而且大多数与大陆的种相同。这些种的分布式样展示我国台湾在区
    系地理上与我国大陆或甚至日本有着比马来西亚地区更密切的亲缘关系。  本文总的结论大
    体上与吴征镒教授关于中国种子植物区系的分区相符,但在某些次要方面有所不同。作者还
    讨论了种的分布式样与自然地理、气候和植被的联系。

Abstract:

A numerical taxonomic study of the distribution patterns of the total 72 species of
Chinese Viburnum using association-analysis method is presented to add some information for
the regionalization of the Chinese flora.  The fact that the center of genetic diversity of Chinese
Viburnum is in the south central part rather than in the southern or southwestern part of China
suggests strongly the subtropical nature of the genus under study.  Southwestern Sichuan is the
most concentrated region of western endemic species.  Inspite of the topographical complexity
of the Hengduan Mountain Ranges, only a few Viburnum species occur in this region.  The
species in Taiwan are largely of subtropical nature and are mostly identical with those on the
mainland.   Their distribution patterns show that the island is floristically more closely re-
lated to the mainland of China or even to Japan than to the Malaysian region. As a whole, the
general conclusions reached here correspond with those of C. Y. Wu for the Chinese sperma-
tophytic flora, yet differ in certain respects of minor significance.  Attempts have also been
made to relate the distribution patterns of species  with physiographic, climatic and  vegeta-
tional conditions in our discussion.
