After the grassland ecosystem is degraded, the recovery process should take recovery measures according to the grassland situation. Grassland degradation can generally be divided into three stages: ① the grass group becomes shorter, the coverage and yield decrease, and if the grassland is properly used or rested, it is expected to recover in a short time; (2) Vegetation composition has changed, and inferior and low-quality weeds and poisonous weeds have proliferated. At this time, certain management measures can be taken to recover in a long time; (3) The grass soil layer was completely destroyed, and then the plant composition and habitat changed, making it difficult to recover.

The process of grassland restoration is actually a process of strengthening management.

First, scientific management. One of the main reasons for the destruction of grassland ecosystem is the lack of scientific and effective management measures for a long time. Strengthening the research on the basic theories of grassland ecology, such as livestock carrying capacity, the best mode of animal husbandry production and scientific management technology, is the first problem that should be paid attention to in the protection countermeasures of grassland ecosystem. Including reforming some backward management policies, implementing moderate grazing, fixing livestock by grass, developing seasonal animal husbandry to reduce the pressure on grassland, providing opportunities for pasture to recuperate and develop grassland vegetation, and implementing scientific management methods.

Second, manual intervention and recovery. Due to the development of animal husbandry and the protection of grassland ecological environment, it is necessary to use artificial grassland and plant feed in order to obtain higher economic and environmental benefits. At present, the area of artificial grassland in China only accounts for 0.4% of the total grassland area, which is only 1/25 of that of the United States and the Soviet Union. According to experts' estimation, planting 0.5- 1% forage grass can increase the total production capacity by 0.5- 1.0 times. It can be seen that the development of artificial grassland industry is a measure that can obtain huge economic benefits in a short period of time and is also conducive to the restoration of grassland ecosystem.

Third, upgrade the system. Modern grass production is a comprehensive undertaking including planting, animal husbandry and aquaculture, and it is also a knowledge-intensive industry. For example, in the process of forage production, it involves scientific research problems such as breeding, introduction and prevention of natural enemies. In animal husbandry, it involves grazing methods, fattening and feeding, and the balance between livestock and grass. The processing and utilization of livestock products should adopt modern biotechnology and comprehensive processing to obtain valuable products, such as cultivating edible fungi, feeding waste and producing biogas. Therefore, the development of modern grass industry in pastoral areas will form a new system of animal husbandry production that conforms to ecological laws and protect and promote the recovery and development of grassland ecosystem.
