Sustainable Development Assessment Based On Improved Ecological Footprint Model Of Zoucheng City

As a new development theory and model,sustainable development has beenalready accepted by many countries and of which the quantitative analysis hasbecome a hot topic.Ecological footprint is one of important methods to analyze andstudy sustainable development by estimating the ecological producing area ofconsumption and absorption of waste in certain region,and comparing with ecologicalproducing area provided by that region to measure the regional economic sustainablesituation.This thesis uses both traditional ecological footprint and Emergy theory to studythe sustainable development of Zoucheng city.Through analyzing ecological footprintand ecological carrying capacity from 2006 to 2010 of Zoucheng,the author presentsthe sustainable development situation of Zoucheng and takes advise about thecomments to the future policy.The result of traditional ecological footprint shows that the Zoucheng’secological footprint per capita seriously exceeds the ecological capacity.The largestecological deficit is in 2010,7.3575 hm2/cap.In the year 2006 to 2008 ,the ecologicaldeficit is constantly decreasing and from 2008 to 2010, the ecological deficit increase.So in 2008 the ecological deficit is the smallest of 6.5763 hm2/cap.In2006,Zoucheng’s ecological footprint per capita was 7.0379 hm2/cap, the per capitaecological carrying capacity is 0.4616hm2/ cap, in 2010 the ecological footprint percapita is 7.8278 hm2/cap, the ecological carrying capacity per capita is 0.4703hm2/cap. From 2006 to 2010, Zoucheng’s ecological deficit per capita trend first decreasesand then increases.On the other hand, the improved ecological footprint based on Emergy theoryshows that Zoucheng is sustaining to be ecological deficit, from 17.2927 hm2/cap in2006 reducing to15.9650 hm2/cap in 2008, and increasing to 17.7708 hm2/ cap in2010.In this five years, the ecological deficit is the largest in 2008 and minimum in2010.Zoucheng’s average per capita ecological is carrying capacity in fluctuation from2006 to 2010.In 2007 and 2010 average ecological carrying capacity is relatively high,mainly because of the 2007 and 2010 pre cipitation is more and makes renewableresources always the value of relatively large. Except for a slight fluctuation in 2007,Zoucheng’s ecological carrying capacity per capita is increasing.The trends of ecological footprint and ecological footprint based on Emergytheory are the same.Zoucheng’s average ecological footprint seriously overpasses theaverage carrying capacity which prove that from 2006 to 2010,Zoucheng’s ecological situation is unsustainable. Combining two theories, we can see a comprehensivepicture of the ecological situation of research region.At the end, the author takes some advise of the analysis and prediction based onZoucheng’s 2006 to 2010 ecological situation and provides the valuable suggestionson how to keep the sustainable development within research region.
