摘  要:
以地处山前平原的河北藁城市种植系统为研究对象 ,从能量利用的角度对该系统能量生产力及其效率和变化动态进行分析。结果表明 ,该市种植系统的能量投入与能量产出同步增长 ,而能量转化效率呈递增递减交替波动 ,尤其近 2 0年来 ,能效呈下降趋势。但从相关的畜牧业及农村经济发展状况看 ,种植业投入能及产出能的增加 ,对土地、人畜力等资源替代作用明显 ,有利于农业大系统持续高效发展

摘  要:
This paper studied cropping system of Gaocheng County of Hebei Province located in Front Mountain Plain.System developing trends of energy productivity, transition efficiency and benefits were discussed from the view of energy use. Results showed that energy input and output of the system were increased synchronously, but energy transition efficiency fluctuated. Especially in the passed 20 years, energy transition efficiency showed decreasing trends. Whereas, viewed from the related condition of stock raising and rural economic development, the increase of energy input and output of cropping system could substitute for resources such as land, manpower & live stock power etc ., which promotes sustainable development of agriculture system.
