Abstract

Abstract:

Ecological footprints (EF) and ecological capacity (EC) in Liangshan prefecture from 2004 to 2011 were studied by using the ecological footprints model. Ecological footprints and ecological capacity in Liangshan prefecture in future were predicted by using the growth prediction model. Results showed that in Liangshan prefecture the per capital EF increased from 0.506 66 hm² of 2004 to 0.593 46 hm² of 2011; the per capital EC increased from 0.873 43 hm² of 2004 to 0.717 70 hm² of 2011; and the ecological surplus constantly decreased. The ecological surplus will turn into ecological deficit in 2015, and the ecological deficit will constantly grow. The efforts for realization of sustainable development in Liangshan prefecture are discussed.

Key words: ecological footprint, ecological capacity, ecological surplus, Liangshan prefecture
