贵州省竹亚科植物区系的初探

THE TENTATIVE STUDY OF THE FLORA OF BAMBUSOIDEAE IN GUIZHOU PROVINCE

贵州迄今已知有竹亚科(Bambusoideae)植物16属60种4变种4变型。本文分析了贵州所产16属竹类植物的分布区类型,并扼要阐述了各属的地理分布与生境。最后讨论了贵州竹亚科植物与邻近地区的关系以及它们在省内各地的分配差异。

It is known that there have been 61 species, 4 varieties and 4 forma of Bambusoideae in Guizhou province, which belong to 16 genera.The genera of Bambusoideae in Guizhou occupy 37.2% of the total genera of that in China. According to the distributional comparative analysis of 16 genera of Bambusoideae in Guizhou, we can divide them into 4 distribution patterns and 5 subpatterns: 1.Pantropic (6.3% of the total in Guizhou); la.Subtropic alpine (6.3%); 2.Asian tropic (6.3%); 2a.Asian subtropic to tropic (l8.8%); 2b.Asian subtropic to temperature (6.3%); 3.Eastern Asia (6.3%); 3a.Sino-Japan (6.3%); 3b.Sino-Himalayan (12.5%); 4.Endemic in China (31.3%). In This paper the distribution and habitats of the genera and species of Bambusoideae in Guizhou were discussed.The Author supported the opinion that Southwestern China to South China is the original region of Bambusoideae. This paper also analysed the relationship between the Bambusoideae in Guizhou and thatin its adjacent regions which showed that the plants of Bambusoideae in Guizhou mainly'distributed in the south, southwestern and north ern areas.
