摘　　要：本文针对四墩子村三种类型家庭草地农业生产结构优化前后的力能学变化进行了研究,结果表明:三种类型家庭生产结构优化后能量转换率、能量产投比都较各自优化前有所提高;三种类型家庭水田投能较为合理,高投高产。而旱田投能较低,产出较低,需加大投入。The energy for three kinds of optimal family productive structure were studied in Yanchi.It indicated:that the conversion rate and input output ratio of energy were higher than ever. The energy inputting in water field is feasible. High output followed high inputting. However, the drought field needs more energy input to prospect more output.
