Abstract:To understand the complexity and stability in grazing systems, the equilibrium and non-equilibrium ecology theory have been developed. The equilibrium ecology theory postulates that, once disturbance has occurred in a system, the system state either returns to its former equilibrium or equilibrates within a new domain of attraction. Clements-Duksterhuis succession theory, from the equilibrium ecology, has provided one basic paradigm for the research on the dynamics of the steppe grazing systems in Xinlin Ri...
