Research of the ecological footprint of the loess plateau of China in 1991

The loess plateau is famous f or its special natural landscape and strong erosion.It has been a hot point regi on of study of domestic and international science.At the same time,the quantitat ive measurement of sustainable development has become one of the frontiers of su stainable development research since the sustainable development concept was put forward.The ecological footprint theory,put forward and developed by W.E.Rees a nd M.Wackernagel since the early1990s,is to measure the human impact on the Eart h and judge whether the human load stays within global carrying capacity.This pa per introduces the theory of ecological footprint,by taking the loess plateau as a case study,it development situation in1991is assessed by using ecological foo tprint theory.The results show that the per capital deficit of ecological footpr int in the loess Plateau was0.6761hm2.The present situation is disadvantageous f or achieving sustainable development.At last,brief comment about the theory of e cological footprint is put forward.
