Abstract: [Objective]The aim of the study was to analyze the energy input,energy output,environmental load rate and index of sustainable development of the oasis agriculture eco-economic system in Aksu region.[Method]by the use of energy theory method from 2002 to 2007.[Result]The result showed that the total energy input,total energy output wre increased year by year.The total energy input in 2007 was increased by 50.7;,compared with that in 2002.The total energy output was increased by 160.13;,in which the output of farm porduction and forestry and fruit growing was faster increased.The energy output of farm production was kept in lower level about 0.05;The environmental load rate was incresaed year by year,which reached 8.32 in 2007,which was 2.97 times as average level of the whole China.The energy index of sustainable development was decreased.[Conclusion]Therefore,the new environmental resources should be proteced and developed to keep the agricultural eco-economic system in the sustainable developing state.
