摘要
生态足迹方法是一种定量评价可持续发展程度的生物物理方法。通过测算人类的生态足迹与生态承载力之间的差距,定量地判断区域的发展是否处于生态承载力的范围之内,为评价区域的可持续发展提供依据。在介绍生态足迹、生态承载力的基础上,运用生态足迹模型对烟台市2002年的生态足迹进行了计算分析,结果表明烟台市2002年人均生态赤字为1.079 hm2,远远超出了其生态承载力,说明烟台市的发展处于不可持续状态。最后,提出了提高区域生态承载力,实现可持续发展的一些对策。
The ecological footprint method is a biophysical assessment method ical capacity, measuring the ecological imperative of sustainability. Human of the human appropriation of ecologconsume products and services of nature; each of us have an impact on the earth. By calculating the difference between ecological footprint and ecological capacity, we can estimate whether it is in a sustainable status or not. This paper introduces the concepts of ecological footprint, the calculation model and the ecological capacity. According to the calculation model, ecological deficit of Yantai is 1.0789 ha per capita, which shows that Yantai City is in a unsustainable status. At last, measures are suggested to increase regional ecosystem＇s carrying capacity and to make the development sustainable.
