摘　　要：内蒙古草地面积广阔,草原资源丰富。作为祖国北方亮丽的风景线和重要的绿色生态安全屏障,内蒙古草地资源不仅为内蒙古经济发展提供坚实的保障,而且对我国文化传承具有不可替代的作用。然而,由于气候变化和人类活动的影响,近年来内蒙古草地资源出现退化的趋势。本文依据174个分布于内蒙古境内的植被空间调查数据,结合历史数据资料,明确草原资源利用现状,分析草地资源退化原因,进而针对草原生态系统特征和具体问题,提出科学、合理、适宜的修复措施。The grassland area in Inner Mongolia is vast and rich in resources.As the bright landscape and essential green ecological security barrier in northern China,Inner Mongolia grassland resources not only provide a solid guarantee for the economic development of Inner Mongolia,but also have an irreplaceable role in the Mongolian culture.However,due to the influence of climate change and human activities,Inner Mongolia grassland resources have been degraded in recent years.Based on 174 vegetation spatial surveys distributed in Inner Mongolia and combined with historical data,this paper clarified the current situation of grassland resource utilization,analyzed the causes of grassland resource degradation,and then proposed scientific,reasonable and appropriate restoration measures for grassland ecosystem characteristics and specific issues.This paper provided a reference for the formulation of scientific and reasonable grassland management policies,and had great practical significance for the sustainable use of grassland resources and the construction of a solid northern ecological security barrier.
