Abstract：Since 1992 the theory of ecological footprint model has been concerned by more and more researchers. In recent twenty years, a great progress has been made in the study of ecological footprint all over the world, especially in China. In this paper we briefly introduced the concept and the calculation methods of ecological footprint, stated its weakness and advantage, and reviewed its research progress abroad and at home. Finally, we argued the possible future research directions of ecological footprint.
