内蒙古中西部草地整治与建立节水型饲料作物基地探讨

An approach into the renovation and establishment in the feed-crop-ground of water-saving type in central-west grassland of Inner Mongolia Autonomous Region

  • 摘要: 阐述了内蒙古自治区中西部草地普遍存在的退化问题,表现为生产力大幅度下降,草群质量降低;土壤裸露化、沙漠化土地面积日趋扩大;河流退缩,绿洲植被濒l临大片枯亡;自2000年以来各地纷纷退耕还草,建立人工饲料作物基地,在实施中又出现人工草地生态系统不稳定。水资源浪费严重,建设成效落后于大面积资源损伤速度以及草地生态安全体系不健全等问题。并提出分片整治与异地育肥、重建草地生态安全保障体系及产业向多元化转移和建设节水型饲料作物基地的整治战略。
