摘 要:
H.T.Odum教授提出的能值理论和方法因有共同的单位（solar emjoules）允许所有的资源在公平的基础上比较,提供了连接生态和经济系统的桥梁,为农业工程的综合分析和评价提供了一个科学的、可行的途径.该文运用能值方法分析了赤峰市绿康公司发展人工草地养殖肉羊的范式.结果表明与内蒙古和中国平均农业发展水平比较,该人工草地生产效率较高（净能值产出率为1.47）,环境压力较小（环境负荷率为2.27）,通过高质量的肉羊舍饲养殖,建立了良好的能值反馈机制,使得该系统实现了生态、社会和经济效益的最大化,可称作为一个小尺度的生态经济持续发展范式,为在内蒙古进行人工草地畜牧业建设提供了一个值得推广的农业模式.[著者文摘]

Abstract:
Synthetical research on the agricultural engineering by applying scientific evaluation system becomes a hot issue at present. Emergy, developed by Odum with the characteristics of common unit ;allows all resources to be compared on a fair basis and provides a bridge that connects economic and ecological systems which supplies a scientific and feasible approach to the synthetic analysis and evaluation of agricultural engineering. So, emergy synthesis was addressed here to analyze the model of developing artificial grassland engineering to breed meat sheep, of Lvkang company in Chifeng city. It showed that the artificial grassland with higher production efficiency with 1. 46 of emergy yield rate （EYR） and lower environment pressure with 2. 32 of evirorrmental load rate （ELR） comparing to average agriculture development of the Inner Mongolia and China constructed good emergy feedback mechanism through yard fattening of high quality and achieved the maximization of ecological, social and economic benefits so that it could be called a small scale paradigm of eco-economic sustainable development and would apply a classical agricultural engineering that is worth spreading for the construction of artifical grasslandstock raising of Inner Mongolia.[著者文摘]
