近20年青岛市生态足迹的动态变化

概括及评述了生态足迹、生态承载力、生态赤字、生态盈余、生态效率和能源生态足迹的计算方法,利用1986年、1995年、2004年3个年度的数据分析了近20年青岛市生态足迹的动态变化。结果表明,近20年青岛市生态足迹增加,生态承载力则明显下降,生态足迹和承载力的变化造成生态赤字进一步加大,同时生态效率也呈增加趋势。提出了通过发展现代科学技术提高生态效率,改变生产和消费方式,优化产业结构,控制城市化发展水平,进行广泛的环境教育等降低生态赤字的可持续发展对策。

Research and Analysis of Qingdao Ecological Footprint Dynamics

The authors summarize and evaluate the calculation process of ecological footprint,ecological capacity,ecological deficit and ecological efficiency,analyze the changes of ecological footprint of Qingdao city in the latest 20 years by using the yearly date of 1986,1995 and 2004.The results show that the ecological footprint of Qingdao rise remarkably,the ecological capacity of Qingdao descend,the changes of ecological footprint and ecological capacity enlarge the ecological deficit,as well as the ecological efficiency rise in the same period.The authors also put forward the countermeasures of reducing ecological deficit of Qingdao city,such as improving ecological efficiency by developing modern scientific technology,changing the mode of the manufacture and consume,optimizing the industry frame,educating widely on environment protection.
