摘　　要：生态城市建设是中国城市转型发展的关键节点,对中国生态文明和新型城镇化发展具有推动作用。研究以中国典型的生态城市厦门市为例,基于城市代谢框架结合能值分析法,对厦门市代谢系统进行各项能值流的核算,构建2010—2017年厦门市能值指标评估体系,选用可持续发展指数、可持续发展能值指标、城市健康水平能值指数3项指标综合评价其生态可持续性,选取部分能值指标与珠海市、深圳市进行对比分析,以期为中国生态城市的可持续发展提供科学参考。结果表明:(1)2010—2017年,厦门市总能值呈上升趋势,2017年的总能值为2.51×10^(24) sej,是2010年总能值的1.65倍,货币流能值显著增加,废弃物流能值下降。能值自给率由98.30%逐渐递增至99.20%,能值产出率由8.30%逐渐递增至15.20%,环境承载率小于3,属于环境低负荷状态。(2)厦门市可持续发展指标处于1—10之间,表明其生态经济系统具有活力和发展潜力,可持续发展能值指标由2010年的3.67增加至2017年的7.76,表明厦门市的可持续发展性能愈来愈好,城市健康水平能值指数由2010年的6.21上升至2017年的25.80,表明厦门市生态系统处于健康可持续发展的状态。(3)厦门市与珠海市、深圳市的能值指标对比分析表明,厦门市与珠海市均处于富有经济活力与生态可持续发展潜力阶段,且厦门市代谢系统的可持续发展水平整体优于珠海市与深圳市。(4)总体来看,厦门城市代谢系统处于可持续发展阶段,生态城市的建设有利于厦门市实现生态经济的可持续发展,研究对同类型生态城市的建设与可持续发展具有理论参考价值。Eco⁃city construction is a key node in China′s urban transformation and development,and plays a driving role in China′s ecological civilization and new⁃type urbanization development.Taking Xiamen,a typical eco⁃city in China,as an example,by calculating the emergy flow of the urban metabolic system of Xiamen,this study constructed an emergy index evaluation system for Xiamen from 2010 to 2017 based on the combined emergy analysis of urban metabolism,selection of emergy sustainability index,emergy index of sustainable development,emergy index of urban health,comprehensive evaluation of the ecological sustainability.Some emergy indexes were compared with Zhuhai and Shenzhen,in order to provide scientific reference for the sustainable development of eco⁃cities in China.The results showed that(1)the total emergy of Xiamen′s metabolic system presents an upward trend from 2010 to 2017,and the total emergy of 2017 is 2.51×10^(24) sej,which is 1.65 times of the total emergy of 2010.The emergy of money flow shows a significant increase,and the emergy of waste is gradually decreasing from 2010 to 2017.The emergy self⁃support ratio of metabolic system in Xiamen gradually increases from 98.30% to 99.20%,the emergy yield ratio gradually increases from 8.30% to 15.20%,and the environmental loading ratio is less than 3,which belongs to the environmental low load state.(2)The emergy sustainability index between 1-10 shows that the ecological economic system has the vitality and development potential.The emergy index of sustainable development increased from 3.67 in 2010 to 7.76 in 2017,showed that the sustainable development of Xiamen is better.The emergy index of urban health rose from 6.21 in 2010 to 25.80 in 2017,showed that Xiamen′s ecological system is in a state of healthy and sustainable development.(3)The comparative analysis of the emergy index of Xiamen,Zhuhai and Shenzhen shows that Xiamen and Zhuhai are both in the stage of abundant economic vitality and great potential of ecological sustainable dev
