How do grazing and stochastic rainfall affect vegetation ? — Insights from a simulation approach

摘要：

Semi‐arid and arid regions are endangered by desertification and degradation on a global scale.Most of the drylands are characterized by unpredictable and stochastic rainfall,so the effects of overgrazing may be masked by rainfall.Due to the stochastic rainfall,the strong dependence of vegetation on rainfall and the lack of empirical long‐term studies on vegetation dynamics it is difficult to separate the effects of grazing and climate without using a modelling approach.
