摘　　要：生态足迹分析法是一种基于区域消费及土地面积的定量研究以衡量研究区域可持续发展程度的新参考方法。本研究以环洞庭湖防护林建设区重点县——岳阳县为研究对象,在阐述生态足迹分析法的基本原理、理论体系的基础上,计算并分析了该县2007年以及防护林体系建设前后的生态足迹。结果表明,岳阳县的生产生活强度已经超过了当地生态系统的承载能力,区域发展基本处于不可持续状态,但是防护林体系建成后,林业生态承载力在总的生态承载力中比重增加,说明防护林项目对维护岳阳县的生态安全,促进区域资源可持续发展起到了重要作用。Ecological footprint analysis is a new developing method in the world to evaluate regional sustainable development based on the calculation of the consumption and quantificational research of land area.In this paper,the basic principle and theory system of ecological footprint was elaborated and also the ecological footprint of Yueyang County before and after construction of protection forest system was practiced and analyzed.The results showed that the developed intensity of production and living in this county went beyond the bearing capacity of the local ecological system,and the regional development was in an unsustainable status.After the construction of protection forest system,the proportion of forestry ecological capacity to the total ecological capacity increased,which meant the protection forest system play an important role in enhancing ecological safety and promoting regional sustainable development in Yueyang County.
