摘　　要：松嫩平原是我国重要的草业和畜牧业基地,具有调节气候,防风固沙和维持生物多样性、保持水土等重要的生态功能。近年来,受自然因素变化和人类活动的影响,松嫩平原草原退化现象日趋严重,制约了该区的草业和畜牧业发展,生态环境也遭到破坏。本文分析了松嫩平原草原退化的原因,整理分析了退化草原的生态恢复方法,为松嫩平原草原保护和恢复提供理论支持。Songnen Plain is an important base of grassland and animal husbandry in China.It has important ecological functions such as regulating climate,preventing wind and fixing sand,maintaining biodiversity and soil and water conservation.In recent years,due to the changes of natural factors and human activities,grassland degradation is becoming more and more serious in Songnen Plain,which restricts the development of grassland and animal husbandry,and the ecological environment has also been damaged.This paper analyzes the causes of grassland degradation in Songnen Plain,and analyzes the ecological restoration methods of degraded grassland,so as to provide theoretical support for grassland protection and restoration in Songnen Plain.
