中国苔藓植物的地理分区及分布类型

The regionalization and distribution types of the bryophytes in China

在对中国苔藓植物相关研究资料进行总结归纳的基础上,对中国苔藓植物的分区进行了重新划分,将最初的7个分区划分为10个分区,从华中区中分出华东区,由华北区中分出华西区,并将青藏区及云贵区内的云南西北部、四川西南部和西藏东南部组成单独的横断山区。就中国苔藓植物的分布类型及可能的分布路线也作了讨论,指出中国苔藓植物的分布路线有3条,一条是从喜马拉雅地区经滇西北、川西沿长江流域到中国的东南部;一条位于喜马拉雅、横断山区和台湾之间;第三条则从喜马拉雅地区通过秦岭直至长白山区。

The original 7 bryological regions of China should be divided into 10 ones according to the distribution of the bryophytes of China. The East China region could be divided from the Central China region, and the West China region divided from the North China region, however the combination of northwestern Yunnan, southwestern Sichuan and southeastern Xizang （Tibet） divided from Qinghai- Xizang region and Yunnan-Guizhou region individually should be the Hengduan Mts region. As well, the distribution of the East Asiatic endemic genera and the endemic genera in China present an oblique distribution line in China, that none endemic genera distribute in Northwestern China and Northern China excluding the three provinces of Northeastern China. During the period of geological history, the distribution of the bryophytes in China might show 3 migrate routes： one of them from the Himalayan region through northwestern Yunnan, western Sichuan to Southeastern China along the Yangtze River, then the second one existed between the Himalayas, Hengduan Mts and Taiwan, and the third one from the Himalayas through Qinling Mts to Changbai Mts.
