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. Two regions could be integrated to the coupling system of the irrigated agricultural region and the rainfeed agricultural region.
