摘要
以兰州市为研究对象,在传统生态足迹模型基础上,采用基于能值分析的生态足迹模型对兰州市2009年的生态可持续状况进行了评价,通过和传统的生态足迹模型的计算结果相比,来验证改进的基于能值分析的生态足迹模型的有效性及可行性,并且和其他省区进行了比较。
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 provinee,Xi＇an city, Xuzhou city, Yunnan province, Heilongjiang province, Shandong province and Xinjiang Uygur Autonomous Regio.
