Abstract: The eastern part of Qinghai province is located in the confluent zone of Qinghai-Xizang plateau and Loess plateau. The natural vegetation in this region is not only connected with alpine vegetation on the Qinghai-Xizang plateau, but also with vegetation types on the Loess plateau; and formed complex vegetation types. They are: desert-steppe, steppe, forest, scrub, high-cold scrub and high-cold meadow. There is an evident vertical zonal distribution of the vegetation. Because of its special geographical position, the distribution of vegetation shows special pattern and landscape. The vegetation types which is connected with Loess plateau, distributes in the river valley and hills, and the alpine vegetation, which is connected with Qinghai-Xizang plateau, on the mountains. Finally, we suggest that vegetation regionizationally, the eastern region of Qinghai province is the transition zone between Qinghai-Xizang plateau and Loess plateau.
