大兴安岭东南麓旱作丘陵区农业生产结构调整与优化

运用线性规划方法分析扎兰屯市、阿荣旗、莫旗的农业生产结构,构建充分体现资源优势,以牛羊为主的农牧结合型调整优化模型.实施该模型,可使农牧业结构进一步优化,上述3市旗种植业总产值分别达到调整前的2.15倍、2.08倍、1.52倍;畜牧业总产值分别达到调整前的1.99倍、1.83倍、1.29倍,经济效益、生态效益和社会效益显著提高.

The adjustment and optimization of agricultural production structure in the dry farming knobs of southeast Daxinganling area

The agricultural production structure of three counties in Inner Mongolia is analyzed in use of liner programming method, and agriculture - animal husbandry - combining adjustment and optimization models were established with cow and sheep raising as the main undertaking in accordance with the advantage of local resources. When implemented, such models can further optimize the structure of agriculture and animal husbandry in the three counties and increase the total output value of agriculture by 2.15 times, 2.08 times and 1.52 times, and that of animal husbandry by 1.99 times, 1.83 times and 1.29 times respectively. So they are greatly beneficial to local economic development, ecological restoration and social progress.
