英文摘要	Land use/cover change is an important theme on the impacts of human activities onthe earth systems and global environmental change. National land-use changes of Chinaduring 2010-2015 were acquired by the digital interpretation method using the high-resolutionremotely sensed images, e.g. the Landsat 80LI, GF-2 remote sensing images. The spatio-temporal characteristics of land-use changes across China during 2010-2015 were revealedby the indexes of dynamic degree model, annual land-use changes ratio etc. The resultsindicated that the built-up land increased by 24.6~103 km2 while the cropland decreased by4.9~103 km2, and the total area of woodland and grassland decreased by 16.4~103 km2. Thespatial pattern of land-use changes in China during 2010-2015 was concordant with that ofthe period 2000-2010. Specially, new characteristics of land-use changes emerged in dif-ferent regions of China in 2010-2015. The built-up land in eastern China expanded continu-ally, and the total area of cropland decreased, both at decreasing rates. The rates of built-upland expansion and cropland shrinkage were accelerated in central China. The rates ofbuilt-up land expansion and cropland growth increased in western China, while the decreas-ing rate of woodland and grassland accelerated. In northeastern China, built-up land expan-sion slowed continually, and cropland area increased slightly accompanied by the conver-sions between paddy land and dry land. Besides, woodland and grassland area decreased innortheastern China. The characteristics of land-use changes in eastern China were essen-tially consistent with the spatial govern and control requirements of the optimal developmentzones and key development zones according to the Major Function-oriented Zones Planningimplemented during the 12th Five-Year Plan （2011-2015）.
