水资源生态足迹分析——以安康市为例

根据生态足迹分析方法,建立了水资源生态足迹概念模型,确定了计算水资源帐户生态足迹所需的3个关键参数,即平均水资源产量、均衡因子和地区产量因子,计算了安康市1996—2007年水资源生态足迹和生态承载力。引入水资源生态足迹压力指数、万元GDP水资源生态足迹、累积水资源生态足迹等指标,利用水足迹模型评价水资源可持续发展程度的全面性和对比性。结果表明,计算结果可客观评价安康市水资源可持续发展与利用情况,为地区水资源的可持续利用与管理提供了科学的依据。

Analysis of Ecological Footprint on Water Resource——Taking Ankang City as an Example

On the basis of the of ecological footprint model,the computational model was built for managing ecological footprint and ecological carrying capacity of water resources.The three crucial parameters including mean yield,equivalent factor,and local yield factor for freshwater resources were determined for evaluating the ecological footprint of water resources.The model was applied to computing the ecological footprint of water resources in Ankang,China from 1996 to 2007.Introducing three indexes:Ecological p...
