青海高寒草甸草地退化的遥感技术调查分析

STUDY ON ALPING MEADOW AND GRASSLAND DEGRADATION WITH REMOTE SENSING TECHNIQUES IN QINGHAI

应用遥感技术探讨了巴颜喀拉山北坡，青海省达日县段退化高寒草甸草地的成因、分布、面积和遥感判译标志，将研究区内高寒草地划分为５个类，２个亚类和３个退化草地型．

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.
