Evaluation of Sustainable Use of Land Resource in Upper Reaches of Minjiang River Based on Ecological Footprint
The sustainable land use in upper reaches of Minjiang river was evaluated using ecological footprint theory and related models to provide scientific basis for ecological agriculture development and formulation of sustainable development policy.The results showed that the per capita ecological footprint,per capita available ecological carrying capacity and ecological surplus in upper reaches of Minjiang river in 2007 were 1.9553hm2,3.3324hm2 and 1.3771hm2,respectively,which showed that the study area was in sustainable development stage.But there were great differences between the various land use types in per capita ecological footprint,arable land was in unsustainable use stage and ecological deficit was found,the others were in the sustainable use stage.
