【摘要】 本文在农业生产一级结构的基础上,根据旱区农林牧综合发展的原则,运用系统工程的理论和方法,模拟了农牧业协调优化模式,认为种植业内部夏、秋、经的比例应由目前的6∶3∶1逐渐转向5∶3∶2,畜牧业的发展应坚持以资源为主,草食家畜为主,中小畜禽为主,大家畜以驴、牛为主的原则。更多还原

【Abstract】 Based on the principle of system engineering and result of agrosystem structure, the optimum coordinated model of subsystem, including farming and animal husbandry was established. It is suggested that best land use structure of summer-crop, autumn crop and economic crop should be adjusted from 6: 3: 1 to 5: 3: 2, and the four emphasis points-resourse, plant-eating livestock, middle and small domestic animal, donkey and cattle must be put forward for the development of animal husbandry.更多还原
