[目的]对新疆阿克苏绿洲农业生态经济系统2002～2007年的能值投入产出、能值产出率、环境负载率与能值可持续发展指标等进行系统分析.[方法]应用能值理论分析方法.[结果]该绿洲农业生态经济系统能值总投入、能值总产出均呈逐年增加趋势,2007比2002年能值总投入增加了50.7%,并以不可更新工业辅助能为主;能值总产出增加160.13%,其中以种植业和林果业产出增长较快;种植业结构从以粮食为主转变为以经济作物为主;能值产出率维持在较低水平,历年来均为0.05;环境负载率逐年增大,2007年达到8.32,是全国平均水平的2.97倍,可持续发展能值指标总体呈下降趋势.[结论]该绿洲环境压力较大,应该保护和开发可更新环境资源,合理利用不可更新资源,使系统处于可持续发展态势.

[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.
