【Abstract】

Fractional Vegetation Cover(FVC)is one of the most important variables in monitoring the changes of terrestrial ecosystems.Based on the Two-endmember model,FVC from 1998 to 2009 in Xinjiang was derived from SPOT VEGETATION Normalized Difference Vegetation Index(SPOT-VGT NDVI).The spatio-temporal vegetation changes were analyzed,and the results showed that:(1)vegetation cover has changed between 1998 and 2009 in Xinjiang,increasing during the first nine years of the 21th century after a continuous decrease during the last three years of the 20th century;(2)vegetation cover increased markedly in the oases,and decreased in some forests,with the most notable decrease occurring in grassland.
