| 中文摘要 |
| 剖析阐述了国际现行能值可持续指标(ESI)中存在的不足之处,拓展构建了新的综合指标(SDI)评价系统可持续发展,实现了能值分析与经济分析和物质分析的耦合.以我国著名的基塘农业生态工程模式——珠江三角洲瓜菜基鱼塘模式为例进行案例分析结果表明,新拓展的SDI能更全面、更明晰地度量被评价系统的可持续发展能力,并指示其能物流及经济流各自的运营状况,为系统的进一步优化指明方向. |
| 英文摘要 |
| Based on the deficiency analysis of current international energy sustainable index (ESI), the new sustainable development index (SDI) was put forward to realize the integration of energy analysis, economic analysis and matter analysis. Taking three dike pond models in Pearl Delta, which is the famous ecological engineering model of China, the case study was carried out. The results showed that the new index can evaluate the system's sustainable development ability more roundly, and showed the station of energy flow, money flow and matter flow at the same time. So it can provide some pieces of constructive optimizing advice from different sides at the same time. |
