摘　　要：生态足迹模型是一种较为实用的评价可持续发展与利用的方法,而能值生态足迹模型在一定程度上弥补了传统生态足迹模型的缺点.该研究利用能值足迹模型对重庆市2007年的可持续发展状况进行评价,结果显示:重庆市2007年实际可利用的人均能值生态承载力为1.602hm2/cap,人均能值生态足迹为6.331hm2/cap,生态赤字为5.729hm2/cap.Ecological footprint model is a good method for evaluating the sustainable development and exploitation of resources.It has been widely used in regional ecological capacity and sustainability estimation.Energy ecological footprint model can make up the deficiencies of ecological footprint.In the present study the energy ecological footprint model was used to evaluate the sustainability of the development of Chongqing in 2007.The results showed that per capita energy ecological footprint was 6.331 hm^2/cap,ecological carrying capacity was 1.602 hm^2/cap,and ecological deficit was 5.729 hm^2/cap.The ecological footprint value exceeded its carrying capacity,which indicated that the social and economic development of the study area was not sustainable.
