摘要：
The Tarim River Basin is the largest and the most arid basin in northwest China, where has an extreme hot and dry climate. The ecological environment of the river basin is especially fragile and vegetation dynamics are very sensitive there. In order to analyze the vegetation restoration effectiveness and provide basic data for ecological research of the river basin, here mapping 30m fractional vegetation cover dynamics in spring, summer and winter from 2008 to 2018 in virtue of cloud computing services of Landsat data provided by the Google Earth Engine (GEE). The average vegetation coverage in summer tended to improve in the Tarim river basin during the past 11 years (R-2 = 0.8744) and the annual average growth rate was 0.35%. The highest vegetation cover occurred in 2017 and increased 58.83% compared to the lowest vegetation coverage in 2009.
