Abstract: The Longwu River in the Qinghai Province is one of the main tributaries of the Yellow River. The Longwu River Valley is one of the important areas of forest resources in the Qinghai Province. Based on the image analysis of the remote sensing data and field investigations, we studied the forest and Shrub vegetation in the Valley. Our results show that this region has some important characteristics of the forests distributed in the marginal zones of the Qinghai-Xizang Plateau. Accordingly, We put forward some proposals on the rational use and conservation of forest resources for this region. Based on the current situation and distributional characteristics of the forest resources, we believe that the conservation and rational utilization of habitat conditions upon which the forests depend are as important as the conservation of forest resources.
