Using ecological footprint method based on net primary productivity( NPP),the ecological footprint,ecological carrying capacity and ecological deficit / surplus in Inner Mongolia in 2005 and 2010 were calculated firstly,and then their temporal and spatial variations were analyzed. Finally,the main driving factors of changes in the ecological footprint were discussed through linear regression analysis. The results show that the ecological footprint increased faster than the ecological carrying capacity in Inner Mongolia from 2005 to 2010,and Inner Mongolia was in ecological deficit on the whole. In addition,the ecological state became worse from the northeast to the southwest in Inner Mongolia,and the ecological state was the worst in Ordos City where the ecological deficit reached 0. 9 km2/ capita in 2010. As a result of increase of industrial intensity and unreasonable industrial structure,the sustainability in Inner Mongolia decreased.
