摘 要:本文采用可利用消化能作指标来计算和衡量草畜平衡,并运用多目标线性规划对乌鲁木齐县灯草沟村的草畜能流转换系统进行优化。优化后的方案与现状相比,经济、社会、生态效益都有大幅度提高。总产值和净产值分别提高了102.30%和113.77%;人均牛羊肉占有量由现状的31.08公斤增加到62.15公斤,各种能量转换效率,以可利用消化能计(A:畜产品产出能/饲草料投入能,B:畜产品产出能/放牧地可利用能;C:畜产品产出能/饲草能;D:畜产品可食能/饲草料投入能),由现状的0.93%、1.12%、0.96%、0.47%分别提高到1.27%、1.57%、1.32%、0.70%.同时,通过系统优化的研究,指出灯草沟村草地畜牧业生产优化模式,为草地畜牧业生产发展规划提供新的方法.The Denchaogou village at Urumqi county is a semi-self-sufficient productive village. which is the natural village of 'taking animal husbandry as guiding, combining with cropping initially'. In Xinjiang, the development of the grassland animal husbandry production has been restricted by the seasonal imbalance between the forage and animals. In this paperwe adopt the available digestable energy as the index to measure and calculate the forage-animal balance, and use multi—objective programming to optimize the system of the energy-flow conversation between, the forage and animals. Being compared with the present sheme, the optimized sheme has obviously improved the economical, ecological and social benefits. At the same time, by studying the optimization of the system, the optimal model of the animal husbandry production of Denchaogou natural village is presented.
