The main performance of grassland degeneration was that the components of grassland became bad

its productivity decreased

the usable grassland reduced and its environment deteriorated in Two West Region. Be- cause of the climate change ) the special terrain in loess plateau

the pest ) disease and mouse in grassland degenera- tion

industry limitation

and management problem and the influence of different situation and micro-biology

the fragility of grassland environment

barren soil and low utilization rate were caused. The principles of managing the degraded grassland were the industrialization of ecological construction

the combination of adjusting measures to local conditions and systematic management

the heavy recovery-medium protection-light utilization and continuity of policy. While its goal was to build the mountain-oasis-desert coupling system in Hexi Region and participate in the construction of Loess Plateau Great Animal Husbandry Base in Dingxi Region respectively.
