退化情况

The result of simulation shows:(1) Different goals of production decision making have different influences on grassland degradation. The production decisions aiming at income maximization is more favorable for relieving grassland pressure that the ones aiming at scale maximization.(2) The effect of herdsman's self-restriction on inhibiting grassland degradation is not less then government mandatory regulation for the grassland utilization;(3) Under the situation of overgrazing, The price rise of livestock products will be helpful to decrease the breeding scale;(4) The application of production technology in risk reduction will be helpful to decrease the breeding scale.

对模拟结果的分析表明：(1)以收入最大化为目标的生产决策比以规模最大化为目标的生产决策更有利于缓解草场压力；(2)牧民的自我约束对抑制草地退化的效果不小于来自政府强制性约束的效果；(3)在目前超载过牧的情况下，价格上涨有助于降低饲养规模；(4)降低生产风险的生产技术进步有助于减少饲养规模。

It is argued that integrated feedback scheduling could maximize resource utilization in underloaded scenarios, and could achieve graceful degradation of control performance under overload conditions. Consequently, the overall control performance could be significantly improved.

该方法在低载情况下可以最大化资源利用，在系统出现过载时可以获取性能的适度退化，因而能够明显改善整体控制性能。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
