资源环境约束下的内蒙古自治区粮食增产问题研究

"十年九旱"的内蒙古,为粮食增产付出的资源和环境成本巨大。因为资源和环境已成为粮食增产的双重瓶颈,又是内蒙古经济社会可持续发展的主要瓶颈。由此,内蒙古要切实加快25°以上坡耕地的退耕还林还草,改善生态环境,发展内涵式的粮食生产方式和节粮型畜牧业,发挥农牧结合的优势,顺应气候变化,从而逐步缓解资源和环境的瓶颈,保障粮食增产,提高农民收入。

Grain Yield Increase in Inner Mongolia Autonomous Region under the Constraints of Resources and Environments

Inner Mongolia paid huge resource and environmental costs for grain yield increase, which was drought nine years out often. Because resource and environment have become not only the double bottleneck of grain yield increase, but also the main bottleneck of economic and social sustainable development in Inner Mongolia. Inner Mongolia should effectively speed up restoring forest or grass of slope land above 25°, improve ecological environment, develop intension type grain production and grain-saving animal husbandry, develop an advantage in combination of agriculture and livestock, adapt to climate change, so as to alleviate the resource and environmental bottleneck, guarantee grain production and enhance farmers＇ incomes.
