The floristic connection between Himalaya and the arctic regions through the central Asiatic highland was supported by the distribution pattern and/or the presence of common or corresponding species with the arctic regions. A term "Central Asiatic Highland Corridor" was proposed to a pass way for the migration of the flora between the arctic regions and the Himalayas as well as E Tibet and SW China.As the result a comparative studies of flora and vegetation it was revealed that :1) There are numerous number of common genera between Himalaya and the arctic regions. But the species composition of floras of both regons is quite different. There are very few common species between them.2) The vegetation types found in the arctic regions were greatly different from those found in Himalaya.3) Cytologically various polyploids were found in the genera which are diversified in both Himalaya and the arctic regions.During our taxonomic studies we found several new taxa in Juncus, Potentilla, Gentiana and others.

喜马拉雅和北极地区之间的植物区系通过中亚高原的分布格局和/或存在的共同或相应的物种与北极地区的支持。本文提出了“中亚高原走廊”的概念，认为这是植物群从北极地区向喜马拉雅地区、从藏东地区向西南地区迁移的通道，通过对该地区植物群和植被的比较研究，发现：1）喜马拉雅地区与北极地区有许多共同属;但两个地区植物区系的种类组成有很大差异。2）喜马拉雅地区的植被类型与北极地区的植被类型有很大的不同; 3）在喜马拉雅地区和北极地区的植物属中发现了多种多样的多倍体植物;在分类学研究中，我们在灯心草属、委陵菜属、龙胆属等植物中发现了几个新的分类群。
