No-tillage reseeding is one of the important measures for improving degraded grasslands. This study focused on three types of temperate grasslands in the Ili River Basin of Xinjiang， setting up no-tillage reseeding and free grazing treatments. The aim was to investigate the effects of short-term reseeding treatment on plant communities， soil physicochemical properties， and plant-soil ecological stoichiometric characteristics， as well as to reveal the ecosystem’s internal stability response mechanisms. The results showed that no-tillage reseeding significantly increased aboveground biomass and community coverage， with community diversity significantly enhanced only in the temperate meadow steppe. The effects of no-tillage reseeding on soil physical properties varied across the grassland types. Plant carbon content significantly increased across all three grassland types， while nitrogen content significantly decreased， and the nitrogen-to-phosphorus ratio of vegetation significantly decreased. Soil organic carbon and total nitrogen both significantly increased， while total phosphorus showed no significant change. The soil carbon-to-phosphorus ratio in the temperate desert steppe and temperate grassland significantly increased， and nitrogen-to-phosphrous ratio increased significantly only in temperate desert steppe. Plant communities of all three grassland types exhibited “absolutely steady state” characteristics. In conclusion， no-tillage reseeding significantly enhanced grassland productivity by promoting community restoration and regulating soil nutrients. The responses of different grassland types to no-tillage reseeding vary， providing scientific evidence and theoretical support for the “differentiated zoning management” of grassland ecological restoration in arid and semi-arid regions.
