摘要

应用能值分析法，以景电灌区沙漠绿洲边缘的一个典型村落--大咀子村为研究对象，对其能值产投结构和指标进行了计算。该村落净能值产出率为3.10，能值投入率为17.38，环境承载力为0.82，能值可持续性指数为3.77，自系统能值反馈率0.39。将研究区的能值指标与江苏省、海南省、甘肃省进行了对比分析，结果表明，系统经引黄提灌后取得了良好的经济效益与生态效益，增强了该区可持续发展的潜力。该区以高投能，种养结合为特点，属干旱区的典型生产模式。针对该区目前存在的一些问题提出了相关对策建议。

Abstract

The theory of energy analysis was applied to select a typical representative village Dazuizi Village located in the desert oasis borderland as a research object.The composition of energy inputted and outputted，energy indices were calculated. Net energy yield ratio was 3.1;energy investment ratio

17.38;environmental loading ratio，0.82;energy sustainable index，3.77;and selfsystem feedback ratio

0.39. Compared withJiangsu，Harman，and Cransu Province

results showed that the system which is irrigatedfrom the Yellow River achievedfavorable ecological and economic benefits and strengthened the potentiality of sustainable develop ment.Production feature was a lot of energy inputted and the combination between planting and livestock breeding.The production mode was typical in arid area

but some problems were still existed. Accordingly

countermeasures and suggestions were presented.
