Main ecological problems of the sustainable utilization of grasslands in China
by Professor Sun Qizhong, Chinese Academy of Agricultural Science

Grasslands cover some 4.0×10⁶ km² or 40% of land in China. Among these, about 3×10⁶ km² , covering 75% is in the grazing region, and the left 25% or 1.0×10⁶ km² is in the farming region..

Presently, the sustainable utilization of Chinese grasslands has been restricted by the land desertification, sharp decrease of grassland acreage, and intensified disaster outbreak, vegetation degradation, loss of biodiversity, serious soil erosion, and etc. Furthermore, there are many technological difficulties in restoring the vegetation for grassland ecosystems, including: lacking high quality forage varieties, some small-scale machines and optimum model for grasslands management. Besides, the system which prevents disasters lacks effective support of technique for resolving the contradictions between the grasslands management and utilization.
