| Abstract: | The ecological footprint theory is a new and popular method to evaluate quantificationally whether the development of a certain region is sustainable,and has been widely applied in almost countries in the world.The model of ecological footprint based on the theory of emergy analysis is a modified style of the conventional ecological footprint,which is used to analyse the regional sustainability.This paper took Lanzhou city as a case and employed the modified ecological footprint to evaluate the ecological sustainability of lanzhou city in 2009 based on the statistic data.While by comparing with the result of the conventional ecological footprint this modified model was examined its effectiveness and feasibility.In addition,the result of the modified ecological footprint of lanzhou city was contrasted with other regions,such as Gansu province,Baiyin city,Jiangsu province,Xi’an city,Xuzhou city,Yunnan province,Heilongjiang province,Shandong province and Xinjiang Uygur Autonomous Regio. |
