Abstract:

Lowcarbon economy is the inner requirement and important path to realize sustainable development for human society.And it is also the inevitable choice to cope with climate change.Firstly,this paper defines the SREE complex system of lowcarbon economy,which consists of society system,resource system,economic system and environment system.And these four subsystem are independent and interrelated.Based on it,the paper builds the comprehensive evaluation index system of complex system of lowcarbon economy. Considering the needs of evaluating the SREE complex system by using the catastrophe progression method, the quantitative indexes are included in the index system for avoiding to determine the weight of the qualitative indexes subjectively.Secondly,the paper evalues the SREE complex system of  lowcarbon economy from 2005 to 2009 in China.According to the result of comprehensive evaluation,the operation curve of the SREE complex system of lowcarbon economy is the wave curve.It is not only the results of double factors,which are international financial crisis and the adjustment of domestic economic structure,but also the results of the mutual influence and interaction of four subsystem. Finally,the paper puts forward the sustainable development strategies of the SREE complex system of lowcarbon economy in China
