The large-scale degradation of grassland ecosystem in the world has seriously affected its production and ecological function. Therefore, the restoration of degraded grassland has become a persistent research focus in the world. Meanwhile, the evaluation methods for the practical effect of restoration are gradually developing and improving. In the process of restoration of degraded grassland, it is helpful to evaluate the effect of restoration practice timely and accurately. This review first summarizes the measures and goals of the restoration of degraded grassland, and then summarizes the evaluation methods of degraded grassland restoration from different organizational scales. In most studies, indicator species, plant community diversity and community structure, VOR and its improvement model, and a series of mathematical analysis methods were used to evaluate the restoration of degraded grassland. By reviewing the application and effects of these methods, it can provide a theoretical basis for the implementation of future degraded grassland restoration practices and the scientific evaluation of restoration effects.
