Offered Papers Theme A: Efficient Production from Grassland

Description

Central China used to be the most important region for animal production, but over-grazing, over- cultivation and deforestation all resulted in a decline in shrub rangeland productivity as well as increasing soil degradation (JiZhou, 1989). Soil erosion, salinisation and desertification have become serious problems. The productivity of shrub rangeland decreased from 3,000~4,000kg/ha to 1,500~2,000kg/ha from the 1960s to the 1990s (Wei, 1991). Since 1990, measures have been taken to solve this problem with promising results.
