目的]通过对井灌区的生产模式进行调查研究,找出伊犁察布查尔县种羊场井灌区农场(户)最优农业生产结构模式.方法]设计了两年三熟+养殖的系统,运用线性规划对模式进行了优化,对6种生产模式进行了评价.结果]两年三熟+育肥牛(羊)模式分别比单独种植小麦模式要高5 479.80(8 959.15)元/2年·hm~2.结论]两年三熟+育肥牛(羊)模式为伊犁河谷南岸大渠的土地开发提供了良好的农业生产模式,不但为减轻天然草场放牧压力提供了解决方案,而且有利于经济效益、生态效益、社会效益的提升,有利于伊犁河谷农业和畜牧业的可持续发展.

Preliminary Discussion on Optimization of Growing,Livestock and Cultivation Structure of Farm

Objective]To find the better structure mode of agricultural production of the Farm in the Jingguanqu of Chabuchaer county of Ili River Valley ,the mode of Jingguanqu were investigated and discussed, Method]some mode about three harvests in two years and livestock were designed, Result]the modes were optimized by linear plan, the six modes were compared and analyzed, the mode of three harvests in two years and the fatiened cattle(or sheep) had better economic returns, ecological benefit and social effects than that of alone mode of cultivate wheat, the income of the former mode is 5 479.80 (8 959.15) yuan per 2 years in one hectare higher than that of the latter mode, Conclusion]the mode three harvests in two years and the cattle(or sheep)can be applied by the people of Ili River Valley, which not only decreased the pressure of grassland,but also enhanced the economic returns, ecological benefit and social effects and were advantageous to the development of agriculture and animal husbandry on both banks of Ili River Valley.
