| 摘 要： | 在生态足迹模型基础上,运用基于能值分析理论的生态足迹模型对徐州市生态足迹进行计算并衡量该区域的可持续发展状况;改进模型将所有自然资源转换为太阳能值进行比较,具有更强的可比性;采用了能值转换率、能值密度等较稳定的参数,更能反映区域特征;采用改进的模型,2006年徐州市能值密度为6.8308E+14sej/hm2,人均生态足迹为8.8551hm2,人均生态承载力为0.2333hm2,人均生态赤字为8.6218hm2,生态足迹远大于生态承载力.

| Abstract: | Based on the conventional ecological footprint, a modified model with emergy analysis was applied to understand the development sustainability.Compared with conventional model, the parameters including emergy transformation rate and emergy density adopted by the new model were more stable, and could better reflect regional character.In the meantime, through translating all the natural resources into solar emergy, the new model was more effective and comparable.By using the modified model, the emergy density... |
