Sustainable development analysis on ecological footprint in Gansu Province

The ecological footprint method is an assessment method of the human appropriation of ecological capacity,for measuring the ecological imperative of sustainability.This research applied the constant global yield method to calculate and analyze the ecological footprint of Gansu province from 1990 to 2007,also analyze development trend of per capita ecological footprint and ecological capacity.The result showed that during 1990 to 2007,the value of per 10 thousand YUAN GDP footprint had a downtrend of velocity deceleration,and footprint diversity varied gradually;the growth trend of ecological deficit will be enlargement from 2007 to 2017 and per capital ecological deficit will be 2.733 hm2.Thus,to form a sustainable development pattern for Gansu,as indicated by the conclusions,the productivity and efficiency of resource utilization should be pushed up to a higher level to enhance the ecological capacity.
