1993-2004年陕西省生态足迹分析与评价

基于生态足迹理论和计算方法,采用联合国粮农组织(food and agriculture organization,FAO)及《陕西省统计年鉴》等自然资源生产与消费、人口、土地等数据,分析了1993—2004年陕西省生态足迹变化情况.结果显示,1993—2004年陕西省出现生态赤字且有上升趋势,2004年人均生态赤字达0.410 7 hm2,表明陕西省生态发展不可持续.有限生态资源的过度利用是产生生态赤字的主要原因.因而,陕西省要维持可持续发展,必须发展循环经济.

Analysis and assessment of ecological footprint in Shaanxi Province from 1993 to 2004

The ecological footprint of Shaanxi Province during the period from 1993 to 2004 is calculated based on the theory and calculation method of the ecological footprint,with the data of resources production and consumption,population,and land use from FAO database and Shaanxi Statistical Yearbook.The result shows that in this period there is ecological deficit each year and the ecological deficit reached 0.410 7 hm~2 per capita of Shaanxi Province in 2004,which indicates an unsustainable ecological development in Shaanxi Province.The conclusion is achieved by further analysis that main reasons resulting in the ecological deficit are increasing use of finite natural resources.It is proposed that the circular economy should be applied to maintain sustainable development of Shaanxi Province.
