Description :
Intensive grazing in spring-summer has been responsible for environmental degradation of the Gurbantunggut Desert in recent years. The coverage of plants and biological crusts, sand surface stability and physicochemical characteristics of soil on the dune surface were conducted in 2002 (winter grazing) and 2005 (spring-summer grazing). Results and discussion about the desert surface activating processes and ecosystem degradation of this region for improving the management of pastureland in desert. It can be seen that grazing season have a significant influence on the sustainable development of the ecosystem in Northwest China.
