免耕补播是改良退化草地的重要措施之一。本研究以新疆伊犁河流域三种温性草地为对象，设置免耕补播与自由放牧两种处理。旨在探究短期补播对植物群落、土壤理化性质及生态化学计量特征的影响，并揭示生态系统内稳态响应规律。结果表明，免耕补播显著增加了地上生物量和群落盖度，群落多样性仅在温性草甸草原中显著提升。土壤物理性质的变化因草地类型而异。免耕补播处理后，植物碳含量在三类草地中均显著升高，氮含量和氮磷比均显著下降，土壤有机碳和全氮均显著升高，全磷无显著变化，温性荒漠草原与温性草原土壤碳磷比显著升高，土壤氮磷比仅在温性荒漠草原中显著升高。三类草地植物群落均表现出“绝对稳态”特征。综上，免耕补播通过促进群落恢复和调节土壤养分，显著提升草地生产力。不同草地类型对免耕补播的响应存在差异，为干旱与半干旱区草地生态恢复的“分区分类治理”提供了科学依据和理论支持。

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.
