Alpine meadows are the key vegetation types of the Qinghai-Tibet Plateau and played critical roles in water-holding, carbon sequestration, and biodiversity conservations for China and Asian. Under the combinations of climate change and over-grazing practices, the alpine meadows have been widely experiencing degradation, which have seriously threatened the strategic status of the ecological barrier of the Plateau. Because of the frigid climate and fragile ecosystem, the rehabilitation of degraded alpine meadows has been a worldwide problem. And the restoration effects of degraded alpine meadow ecosystems also vary with the degraded gradations, restoration measures, and natural climatic conditions. The typical multi-path restoration measures such as grazing time management (spring rest-grazing and autumn rest-grazing), grazing intensity management (grazing livestock community optimization, rotation-reduction grazing, and fence enclosure) and tillage reconstructions were surveyed to explore the responses of key ecological variables and their underlying ecological processes of the degraded alpine meadows. The results showed that aboveground biomass, belowground biomass, soil organic carbon, and soil saturated water contents of degraded alpine meadows were clearly promoted under the multi-path restoration measures. The restoration effects varied with treatment durations and specific measures. Comparing with autumn rest-grazing, spring rest-grazing could be a better option of grazing time management for lightly and heavily degraded alpine meadows. The ecological functions of soil carbon sequestration and water holding capacity under fence enclosure and tillage reconstruction showed a positive but saturating logarithmic relationship with treatment durations. And their appropriate durations in ecological restoration of the degraded meadows was about 6-10 years. For heavily degraded alpine meadows, the fence enclosure should be first adopted for 6-10 years and then grazing livestock community optimization and rotation-reduction grazing could be later used for the balance between ecological function and stockbreeding development. Therefore, the restoration measures of grazing time and intensity management should be mainly applied to alpine meadows with lightly and heavily degradation. As for extremely degraded alpine meadows, generally referred to as "black soil beach", the tillage reconstruction would be an appropriate measure. Soil carbon sequestration and water holding capacity was significantly promoted after 6-year tillage planting treatment. Due to the different initial targets of multi-path restoration measures, future researches should focus on the scientific combinations and comprehensive assessments of restoration measures. Those countermeasures should take the restoration staff and time costs and ecological rehabilitation efforts into full considerations and balance the function of ecology, production, and livelihood of alpine meadow ecosystems.
