太行山区小流域生态足迹研究

将生态足迹的理论与方法应用于山区小流域的可持续发展研究，实地调查走访小流域农户获取了大量的有关小流域生产和生活方面的数据，计算了小流域的生态足迹和生态承载力。2005年黄塔小流域人均净生态足迹需求为1．681hm^2，可以提供的人均生态承载力为1．938hm^2，人均生态足迹有赢余0．257hm^2，而小流域对外贸易调整前的人均生态足迹为2．210hm^2，人均赤字0．272hm^2，说明对外贸易对小流域生态系统的稳定性影响很大。把小流域与小流域附近的河北省怀来县及北京市、我国东部地区、全国、全球进行了比较。表7，参21。

Study on Ecological Footprint of small watershed in Taihang Mountain

The "ecological footprint" method was used to study sustainable development of mountainous small watershed.Data of productive and life consumption about small watershed was required by local farmer investigation,and ecological footprint and ecological carrying capacity of small watershed was calculated.The per capita ecological footprint was 1.681 hm2,per capita available ecological carrying capacity was 1.938 hm2,and ecological surplus was 0.257 hm2.The per capita ecological footprint before external trade balance was 2.210 hm2,and the ecological deficit was 0.272 hm2.The results showed that external trade had an influence on stability of ecological system of small watershed.The Small watershed was compared with its nearby Huailai county of Hebei province,Beijing city,eastern China,China and the World.
