| 摘 要： | 用数学方法对放牧影响草场的因子进行了量化，定量地研究了放牧强度对草场的影响，在已知草场的基本情况下，建立草场退化程度与放牧强度之间的关系，用实例分析说明了牧畜超载对草场的破坏程度，对放牧强度R值的分析表明，只有调整放牧强度或减少牧畜头数，才能减缓放牧对草场的破坏和压力。

| Abstract: | In this paper, the factors that affect grassland is measured by way of calculation,and grazing intensity affects grassland is studied by mathematics method.Based on the basic condition of grassland,linearity relationship between grassland degeneration degree and grazing intensity is established. Using example to explain livestock's overtake caused destruction to grassland. Modulating grazing intensity and reducing livestock according to analyzing R, and then decreasing livestock's destruction and pressure to the grassland. |
