Discussion on Landscape Ecosystem Planning of Small Basins in the Qinghai-Tibet Plateau——Taking Nieruzangbu Basin as an Example

In this paper, taking Nieruzanghu as an example, it is discussed that how to plan landscapes of small basin in the Qinghai-Tibet Plateau. With analyzed the status and character of landscape structure through the use of landscape diversity indexes and landscape dominant indexes, some major problems in the landscape ecosystem are pointed out. On the basis of regional restrictive principle and compliance principle of resources, environment and economy, Nieruzangbu Basin is divided into three landscape function areas. According to the demands of each function area, landscape structure planning is carried out to improve ecological environment through optimization and adjustment of landscape structure in Nieruzangbu Basin.
