Sustainable development of the population-resources-environment relations in Xinjiang,China

Based on the emergy analysis theory,we choose some emergy indices such as net emergy yield ratio(NEYR),emergy investment ratio(EIR),environmental loading ratio(ELR),emergy dollar ratio(EDR),emergy density(ED),fraction of emergy used from electricity(FEE) and emergy-based sustainability index(ESI) to assess the eco-economics system sustainable development situation of Xinjiang by the change tendency of Xinjiang NEYR,ELR,EIR and ESI indices from 1996 to 2005 and the comparisons between other countries and regions.It could be concluded that to realize the objectives of the sustainable development,that is to maximize the whole system power yield as well as the minimize the environment negative effects;the system should adjust its economic structure to optimize the self-organized situation.The change tendency of ESI has a close relation with the economic growth of Xinjiang.To keep the sustainable development index steady decrease,the government of Xinjiang should takes a peer efforts to focus on economic growth and control eco-system's press on environment,and the best way is to develop circular economics.
