| 摘 要： | 采用能值分析方法,构建了基于城市物质代谢通量指标、代谢存量指标和代谢效率指标的城市物质代谢指标体系,并以北京、天津、上海和重庆四个直辖市为例计算了2005年四城市物质代谢状况。分析结果表明:北京市代谢效率最低;上海市代谢通量和代谢存量最大,但是代谢效率不容乐观;重庆市代谢通量和代谢存量在四个城市中居于末位,但是代谢效率最高;天津市在四个城市中代谢呈中等水平。最后根据分析结果对城市今后的可持续发展提出了意见和建议。

| Abstract: | Based on energy analysis,an index framework of urban material metabolism including metabolic flux,metabolic stock and metabolic efficiency was proposed,by which the urban material metabolism level of four municipalities in China including Beijing,Tianjin,Shanghai and Chongqing in 2005 were investigated and analyzed.Results revealed that metabolic efficiency of Beijing was the lowest while Chongqing was the highest and the condition of Shanghai was not satisfied.The metabolic flux and metabolic stock of Shan... |
