| Abstract: | Remote sensing tecinigues were used to study the causes, distribution, areas and the interpretative keys of the degraded alpine meadow and grassland in the Bayankela Mountains, Dari county, Qinhai. The alpine grassland was divided into 5 types and 2 subtypes, and 3 degraded grasslands. Special emphasis was paid to analyze the causes of the degradetion and interpretative keys of landsat image. |
