半城市化地区可持续性评价——以厦门市集美区为例

Sustainability assessment in peri-urban area:a case study of Jimei District in Xiamen

在快速城市化过程中,评估半城市化地区可持续发展状况对引导其城市化良性发展有重要意义.论文以厦门市集美区为研究对象,利用改进后的生态足迹模型计算了集美区2004～2006年生态足迹的时间序列变化,着重分析了2006年生态足迹与生态承载力的关系.结果表明,2004～2006年间,集美区人均生态足迹呈现不断上升的趋势,每万元GDP的生态足迹逐渐减小,这说明集美区的资源利用效率和生物生产的产出率正逐渐提高,经济发展模式正由粗放、耗能型向集约、科技型转变.然而,2006年集美区总生态足迹仍是其生态承载力的6.8倍左右,处于严重的生态赤字状态.

To evaluate the sustainabitity of peri-urban area is significant in leading its sound development during the fast urbanization process. We estimated the ecological footprint and analyzed the trends of change from 2004 to 2006 by using modified model and taking Jimei District in Xiamen for example, and particularly compared the relationship between ecological footprint and ecological carrying capacity in 2006. The results indicated that during 2004-2006, the ecological footprint per capita tended to increase, while the ecological footprint per ten thousand yuan GDP tended to decrease, which showed the increasing pressure of resource and environment due to urbanization process. However, the extensive and energy-based economic development mode of Jimei District was changed into an intensive and technology-based one. The ecological footprint was about 6.8 times more than ecological carrying capacity, which showed Jimei was in severe ecological deficit.
