摘要
应用能值分析方法对农业生态经济系统的能值投入及产出结构进行了研究,通过计算建立了能值指标体系,并与不同地区进行了对比,得出环境负载率和能值投资率2个重要的能值指标在计算和对比中还存在较大差别,需要进一步深入研究。
The energy analytic method was applied to study the structure of energy inputs and outputs of agricultural eco-economic system.The energy index system was established by calculating,and it was found that the main two energy indices environmental loading ratio and energy investment ratio had great differences as compared with those in different regions,which needed further study.
