摘要:
生态足迹是一种衡量一个国家或者一个地区可持续发展状态的方法，定量反映人类活动对生态环境的影响和破坏程度。在对传统生态足迹模型进行简要分析的基础上，本文提出了基于能值分析理论的生态足迹计算的改进模型。本文运用能值足迹模型对舟山市1985~2011年的生态足迹进行计算，得出舟山地区的生态足迹和生态承载力。结果表明，舟山市的生态足迹长期处于亏损状态，达不到可持续发展的要求。造成这种情况的主要原因在于，在近年来，占舟山生态足迹主要位置的水产业由于过度捕捞等原因对舟山市的生态环境产生了很大的影响。
Ecological footprint is a method for measuring sustainable development degree of a country or re-gion, quantitatively reflects the destructiveness and influences degree of human activity on eco-logical environment. A modified model for ecological footprint calculation is put forward based on the energy analysis. In this paper, we use the Energy Footprint Model to calculate the ecological footprint of Zhoushan from 1985 to 2011. The result shows that the ecological footprint is in a deficit situation for a long time, and cannot reach the requirements of sustainable development. The reason why this situation happens is that, overfishing has a huge impact on Zhoushan ecological environment.
