摘要: 城市生态足迹分析可定量反映城市人类活动对自然生态环境产生的压力和影响程度,这种方法为城市生态系统研究提供了新的思路和研究方向。本文在介绍生态足迹的理论和计算模型的基础上,以台州市为例,计算了台州市2002年的生态足迹。结果表明,2002年台州市生态足迹为1.33084 hm2·人-1,可利用的生态承载力为0.25800 hm2·人-1,生态赤字为1.07284 hm2·人-1,反映了台州市的生产、生活强度超过了生态系统的承载能力。因此,台州市需注重提高其资源利用效率,提倡节约型的生产和生活消费模式,减少其生态足迹,通过生态城市建设,实现城市的可持续发展。

Abstract: Urban ecological footprint can quantitatively reflect the stress and the effects of human activities on urban ecosystem, by which, the health situation of urban ecosystem could be judged. Taking Taizhou City as a case, its ecological footprint in 2002 was calculated. The results showed that in 2002, Taizhou City had an average ecological footprint of 1.33084 hm2 and a per capita available ecological carrying capacity of 0.25800 hm2, with an ecological deficit of 1.07284 hm2, which suggested that the carrying capacity of the urban ecosystem in Taizhou was under great pressure. To make Taizhou City step toward eco-city and achieve sustainable development, policymakers should make efforts on improving resources use efficiency, calling for saving-pattern production and consumption, and trying lessening ecological footprint in the future ecological construction.
