甘南黄河源区生态足迹研究

On Ecological Footprints of Yellow River Source in Gannan Zang Autonomy Region

应用生态足迹的方法,以甘肃甘南黄河源区“中华水塔”的统计年鉴为资料依据,在对该区进行了现地考察以后,将该区域划分为三个功能区:重点保护区、修复治理区和生态经济示范区。分别对三个功能区的生态足迹进行了计算和分析,得出结果:重点保护区的生态承载力略有盈余(1.4644),而生态经济示范区的生态承载力出现亏损(-0.8230),修复治理区的生态承载力介于两者之间,略有盈余(0.2312)。通过生态足迹的研究,提出了甘南黄河源区进行可持续发展过程中应采取的对策措施。

This paper introduces the concept of ecological footprints and a calculation method,and calculates the ecological footprints in the Gannan Zang Autonomy region （China Tower）after field survey. This region was divided into three functional areas,they are： the focus ecologically protected zone,the renovated area and the demonstrated zone of ecological economy. The results are as following：the focus ecologically protected zone appears surplus（1.4644） while the demonstrated zone of ecological economy bears deficit （-0.8230）,the renovated area is at midst,a slight surplus （0.2312）. After analyzed the causes of the changes in its ecological footprints. This paper also provides some measures for solving the problem in the Garman Zang Autonomy Region,and a model for sustainable development and economic promotion is proposed from the research results.
