Abstract By comparing the grass productivity and plant characteristics in early 1980s and early 2000s in Naiman County in Horqin Sandy grassland, we analysed the degradation of sandy grassland which existed in this place. On the study of climate changes between 1963 and 2002 and development of animal husbandry between 1947 and 2002, the main reasons for the degradation of sandy grassland was analysed . The results showed that the rapid degradation of sandy grassland resulted in both the changes of climate and human activities, especially irrational animal husbandry mode, the changes of climate accelerated the degradation of eco-system of sandy grassland.
