Rotational grazing is an effective way to improve grassland resources utilization and develop animal husbandry. Rational grazing scheme can avoid eco-environment damage caused by overgrazing, and it can ensure the livestock normal feeding. The rationality of rotational grazing management is affected by many complex and dynamic factors. This paper establishes a model of rotational grazing assignment based on grass resource leveling. Firstly, each rotational grazing plot’s forage yield in each rotational grazing assignment stage is predicted by seasonal prediction method. Then, constrained by the rotational grazing plots’ forage yield and livestock’s forage demand, a dynamic rotational grazing assignment model is established, which combines the assignment model and carrying capacity constraint. Thus, the maximum edible forage in a rotational grazing cycle is contained and the distribution of the corresponding rotational grazing plots is determined. In each rotational grazing cycle, each rotational grazing plot can only be assigned once, which embodies the principle of ecological protection. And livestock have as much forage as possible in a rotational grazing cycle. Finally, through a case analysis, a feasible solution in a rotational grazing cycle is obtained. Through taking carrying capacity in each rotational grazing assignment stage as a standard to scheme the grazing order in each plot, the uncertainty of eco-environment is better reflected. A reasonable decision scheme of dynamic rotational grazing can make resources used efficiently in time and space.
