The degradation of 60% of the world′s grasslands and 70% of China′s grasslands is a serious threat to sustainable socio⁃economic development. The current approach of “enclosure instead of improvement” blocks the natural connection between grassland and livestock and promotes the decoupling of livestock⁃environment⁃plant⁃human interactions. Grassland improvement is to solve the fundamental contradiction of seasonal imbalance of grass⁃livestock supply and demand through a series of management measures under the guidance of the theory of grass science, to promote the sustainable development of ecosystems and enhance the well⁃being of human beings. According to the target of improvement measures or their scales and attributes, there are five classification methods for the implementation of improvement measures. Main methods include enclosure, grazing, ripping, over seeding, fertilization, irrigation, fire, grazing, artificial rain enhancement, research tourism, intelligent management, policies, and regulations, etc., and the integration of grass⁃animal feedback mechanisms through changes in the grass system or its components. Grassland improvement follows the principles of industrialization, careful transformation, comprehensiveness, and scale correspondence, requires synergy or superimposition between integrated technologies, with effects reaching super saturation or surplus saturation. Grassland management is divided into an improvement period and a utilization period, which corresponds to the state of health of the grassland. The utilization period and improvement period of grassland always interact and constrain each other, so it is especially crucial to deal with the relationship between these two. The key to grassland improvement is to determine the thresholds of ecosystem response to the adaptation, response and saturation periods of the improvement measures. The degradation trend of grassland can be predicted in advance, and appropriate improvement measures can be taken at critical points to restore the grassland to a healthy. Ecological processes of the grassland improvement and utilization periods are not independent of each other, but are integrated and promoted. The improvement period can be reasonably utilized, while the utilization period can also be improved according to local conditions. Attaching importance to “harmful” organisms as irreplaceable components of the ecosystem and their resource properties, clarifying the ecological and economic thresholds for their prevention and control. Establish a standardized grassland improvement process based on the health level of grassland, which not only reduces the threshold of entry, but also promotes intelligent, mechanized, and large⁃scale operations. On the basis of the traditional improvement of “grass” and “land”, emphasis is placed on the improvement of “livestock” and its relationship with other components of the grass system, and ultimately the cultivation of the grass system is realized.
