Abstract: The urban land cover structures play an important role in providing urban ecological service and altering the quality of human settlements environment.In this study锛�2000~2015 Landsat TM series satellite data along with fine resolution remote sensing images were used to capture information of each 5-year land cover structures in 12 prefecture-level cities of Inner Mongolia Autonomous Region.Subsequently锛宼here land cover information was used to monitor and analyze the spatiotemporal dynamics of urban expansion锛宎nd differences of land cover structures and expansion types.The results showed that锛歩n 2000~2015锛宼he overall changes of land cover structures in 12 prefecture level cities of Inner Mongolia Autonomous Region were rapid.Specifically锛宼he urban area expanded by 278.93 km2.By comparison锛宼he proportion of urban area expansion in 2010~2015 was 1.61 times and 1.91 times than that of the first two periods (in 2000~2005 and in 2005~2010).Since 2010锛宼he most dramatic changes has been observed.Particularly锛宱bvious urban impervious surface expansion was found.Also urban vegetation showed obviously increased with varying degrees.At the past decade锛寀rban expansion has undergone three stages.Specifically锛宼he main process experienced from urban interior filling to urban interior filling and then to urban extension锛宱f which Baotou and Hulunbeier belonging to the internal filling city.Population growth and socio-economic development are responsible for these differences.

Key words: Urban land cover, Impervious surface, Prefecture-level cities of Inner Mongolia Autonomous Region, Remote sensing
