Abstract: The farming-pastoral ecotone in Inner Mongolia is the main body of the farming-pastoral ecotone in nothern China. In the past few decades, due to the over-exploitation and irrational use of cultivated land, combined with natural and human taetors such as climate change, the cultivated land in the farming-pastoral area of Inner Mongolia has experienced ditterent degrees of degradation. In some areas the cultivated land has been basically unable to produce. Therefore, promotion of the sustainable use of cultivated land in the farming-pastoral area of Inner Mongolia is the foundation of the development of agrieuhm＇e and animal husbandry in Inner Mongolia. The causes and eurrent situation of cultivated land degradation in the farming-pastoral ecotone in northern China, and the research and application of ecological conservation and restoration techniques tor degraded thmlland in Inner Mongolia in the past 20 years were systematically analyzed in this paper. The key technologies suitable tor ecological restoration of degraded thmlland in Inner Mongolia were put torward to provide strategic thinking, technical guidance and practical theoretical support tor the ecological conservation and sustainable use of degraded farmland in Inner Mongolia.
