| 摘 要： | 通过生态足迹的概念和模型的引入,阐明肇庆市生态足迹研究的必要性及紧迫性。并以肇庆市2003生态足迹研究为基础,进一步分析了1990-2003年间肇庆市生态足迹的变化趋势。结果表明,肇庆市人均生态足迹和生态赤字呈不断上升的趋势,人均生态足迹高于人均生态承载力,人类对自然的利用程度已经超过了生态承载力范围,区域生态环境目前处于不可持续发展的状态。

| Abstract: | Based on the introduction to the concept and calculation method of ecological footprint indicator,ecological footprints in 2003,and the change of ecological footprint from 1990 to 2003 in Zhaoqing were studied.The results showed that ecological footprint and ecological deficits per capita had quickly increased during 1990-2003.The ecological footprint per capita of Zhaoqing city has gone beyond the regional bio-capacity,and human s utilization of nature beyond the regional ecological capacity.Zhaoqing city is nowin a condition of unsustainabledevelopment. |

| Keywords: | ecological footprint type of ecologically productive area bio-capacity ecological deficit ZhaoqingCity |
