摘　　要：基于能值生态足迹模型分析2005—2009年广州城市生态足迹和生态承载力,利用万元GDP足迹及可持续生态指数评价广州市发展的可持续性。研究结果表明,2005—2009年间广州生态足迹相对平稳,长期处于生态赤字状态。随着GDP的上升,生态消费总足迹和本地产出生态承载力都有下降趋势。可持续指数平均值为0.53、接近0.5,表明广州生态足迹和自然生态承载力大致相当,区域可持续发展性接近边缘状态。同时,据此提出广州可持续发展的建议。The paper analyzesd the city ecological foot-print and ecological capacity of Guangzhou in 2005—2009 based on emergy ecological footprint model.In order to reveal human and natural role fully and accurately,this model includesd consumption ecological foot-print,local products bearing capacity and natural capacity.This paper made use of ten thousand yuan GDP and sustainable ecological index to evaluate the sustainability of the development in Guangzhou.The result showed that： during the time of 2005—2009,ecological foot-print of Guangzhou was comparable steady in an ecological deficit situation.Along with the rise of GDP,however,the total ecological consumption foot-print and local output ecological capacity appears downtrend.The average index of sustainability was 0.53,close to 0.5.It meant that ecological foot-print almost equals to natural ecological capacity in Guangzhou,the sustainable development comes near to a rim condition.The suggestions for sustainable development in Guangzhou were proposed.
