In this study,3 Landsat satellite images at the end of summer of 2000,2010 and 2016 in Zoige County were taken as the main data source.With the support of remote sensing image processing software(ArcGIS 10.2 and ENVI 5.3)and landscape analysis software(FRAGSTATS 4.2),the characteristics of landscape pattern change,the conversion between various landscape types and landscape index change in Zoige County from 2000 to 2016 were analyzed by using the theory of landscape ecology.The study indicated that,1)from 2000 to 2010,the frequency of transformation between patch types in the study area was relatively high,mainly reflected in the conversion of other landscape types to grassland,the area of marsh and lakes began to shrink,and the landscape like sand and desert became grassland on a large scale.2)From 2010 to 2016,the variation trend of landscape transformation was significantly reduced,and the area of marsh and lakes was restored.3)Overall,the basic landscape pattern of the study area did not change significantly,grassland was the most dominant landscape type in the study area,the area and heterogeneity of roads and residences continued to increase.
