英文摘要	Based on the LandsatTM/ETM+/OLI remote sensing data (30 m resolution) of the Shule River basin in the past 20 years, the land use data was obtained by interpretation. By using Erdas9.2 and ArcGIS10.3 software, the land-use types were divided into 6 primary landscape types and 25 secondary landscape types, and the spatial database of watershed land use was established. By using GIS spatial analysis technology, transfer matrix, land use dynamics and many other spatial-temporal statistical analysis methods, the transformation process and temporal and spatial pattern analysis of land-use types in river basin in recent 20 years were carried out, with results showing that: In the past 20 years, different degrees of changes have taken place in land use in the Shule River basin. On the whole, the area of cultivated land, woodland, grassland and urban and rural industrial and mining residents increased, among which grassland increased the most, with an annual increase rate of 0.33%. The area of cultivated land increased, with an annual growth rate of 0.0959%. While water area and unused land decreased, with an annual decline rate of 0.4490%. The decrease of water area was the smallest, with an annual decline rate of 0.0122%. There are obvious differences in the speed and type of change in water area and unused land. The hot spot of land use type transformation in the basin is the middle reaches oasis, mainly Dunhuang, Guazhou and Yumen counties (cities).
