【Abstract】 After a brief introduction to the history, fundamental concept, method and steps of emergy theory and analysis method, the current situation and future trends of six frontiers of emergy study are reviewed anddiscussed. The six frontier fields in emergy study include: applied research, emergy theory and the optimization of evaluation system, the integration study of emergy in connection with landscape ecology and otherthermodynamic theory, measuring method, and unification of emergy transformity.更多还原
