摘  要:能值理论、方法克服了传统能量与经济分析方法的诸多缺憾 ,为城市可持续发展的研究提供了全新的视角。但作为一种新兴的理论 ,其评价指标 ,尤其是针对城市可持续发展能力的综合评价指标尚不完善。从生态经济效益及环境影响的全面表达角度 ,剖析了国际现行可持续发展能值指标 ( ESI)的不足之处 ,并在此基础上拓展构建了新的可持续发展能值指标 ( EISD)。以珠江三角洲中山市 1 996~ 2 0 0 0年的发展动态为例进行了案例研究。结果表明 ,新拓展的可持续发展能值指标 ,在系统效益评价中考虑了系统能值产出的实际经济效果 ,在环境影响评价中同时考虑了系统的消耗影响和排放影响 ,可以更全面明晰的评价城市系统的可持续发展能力、状态及其成因 ,为系统的优化指明方向。The evaluation of the sustainable development ability of urban ecological economic systems quantitatively has been more and more highlighted, following the non-invertible urbanization trend of the world. New methods are needed to solving the interface problem between nature and economic society. Founded by H.T. Odum, emergy synthesis has been seemed as a bridge between natural and economic system. Broken through the “energy quality wall” of traditional energy theory, emergy theory realized the unified assessment of energies with different quality and type and moved the energy analysis into a new phase. But the emergy indices system for this evaluation is still young and need to be improved. The establishment of Emergy Sustainable index (ESI) and its quantification partly covered the gap of emergy index for sustainable development and promoted the study of sustainable development. However, the sub-index which it used to express the sustainable benefit is not always beneficial and helpful to our sustainable development, limited by our current knowledge and technology. Simultaneously, the sub-index which it used to express the environmental impact can only reflect the consumption structure of resource, leaving the environmental impact of expelled pollutant be neglected. This paper is a study on emergy indices for the evaluation of urban's sustainable development ability. Based on the deficiency analysis of ESI and the concept of sustainable development, a new Emergy Index for Sustainable Development (EISD) is deduced. Employing EISD, a case study is conducted to evaluate the development of Zhongshan city Pearl Delta, during 1996 to 2000. The result is that the EISD of Zhongshan had appreciably declined from 0.1573 in 1996 to 0.1510 in 1998, and quickly improved from 0.1510 in 1998 to 0.1785 in 2000. The consume structure of Zhongshan city was less and less depended on nonrenewable resource come from local natural or purchasing, with its Environmental Loading Ratio (ELR) decreased from 5.2761 in 1996 to 3.6769
