Energy balance analysis of integrated crop‐livestock production system in Tianshui town,Huanxian county of Gansu province

摘要：

Energy balance analysis is a useful approach for assessing the sustainability of farming systems.Energy used on a farm include energy that is used for production inputs ( eg.fertiliser, labour, seed) and production outputs ( eg.grain from crop, meat and wool from livestock production).Energy balance is measured by energy efficiency‐the ratio of energy output to energy input.The higher the value is, the greater the energy efficiency is.This paper presents the results of an energy balance analysis for Tianshui town (37.12°N 和106.82°E) in Huaxian County, Gansu Province, China.
