生态足迹模型自1992年提出以来,世界各国的学者对模型的完善进行了大量的研究,使其在评价某一区域的可持续发展程度方面已经得到广泛的应用。本文介绍了利用地区投入产出表来计算生态足迹的新方法,并用此方法对湖南省2002年与2005年的生态足迹。分析了导致各部门生态足迹增长的可能原因以及造成各部门万元GDP生态足迹降幅不同的原因。运用结构路径分析法,指出在湖南省各产业部门之间的联系非常密切,政府部门应将三部门经济联合起来考虑,从而制定出旨在减少生态足迹实现可持续发展的政策和规划。
Since the ecological footprint model was proposed in 1992, scholars all over the world have done a great deal of research on the perfection of the model and have made it widely used in evaluating the sustainable development of a certain region. This paper introduces a new method to calculate the ecological footprint using the regional input-output table, and uses this method to analyze the ecological footprint of Hunan Province in 2002 and 2005. Analyzes the possible reasons that lead to the growth of ecological footprint in various departments and the reasons for the different decline of ecological footprint in each sector. By means of structural path analysis, it is pointed out that the links among the various industrial sectors in Hunan Province are very close. The government departments should consider the three sectors of the economy together to formulate policies and plans aimed at reducing the ecological footprint and achieving sustainable development.
