title: [Extending study on energy indices for sustainable development].
abstract: 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.
