Understanding the influences of grazing exclusion (GE) on soil properties and vegetation characteristics is essential for the assessment of grassland restoration. The objectives of this study are exploring the efficiency of short-term GE in restoring alpine meadow in the Zoige region, eastern Tibetan Plateau, with high rainfall amount. We conducted sampling surveys before and after one-year GE in alpine meadows with seven sequent degraded degrees. The results showed that one-year GE significantly increased soil organic carbon (SOC), soil total nitrogen (STN), soil water content (SWC), and plant biomass, while decreased soil bulk density (SBD) regardless of the degradation degree. These findings suggest that short-term GE may be an effective way to restore degraded alpine meadow. Aboveground and belowground biomass was significantly positively associated with SWC, SOC, STN, soil total phosphorus, and soil available nitrogen, but presented negative relationship with SBD. This shows the complicated interaction between vegetation and soil physiochemical properties that regulates the grassland recovery process. The degraded alpine meadow in this rainfall-rich region could rapidly recover once grazing disturbance was excluded. This study can provide technical support for restoration and sustainable management of alpine meadows on the Tibetan Plateau.

了解放牧对土壤特性和植被特征的影响对于评估草地的恢复至关重要。这项研究的目的是探索短期GE修复高降雨量的Zoige地区高寒草甸的效率。在一年的GE发生前后，我们对七个连续退化程度的高山草甸进行了抽样调查。结果表明，一年的GE显着增加了土壤有机碳（SOC），土壤总氮（STN），土壤水分（SWC）和植物生物量，而降低了土壤容重（SBD），无论其降解程度如何。这些发现表明，短期GE可能是恢复退化的高山草甸的有效方法。地上和地下生物量与SWC，SOC，STN，土壤总磷和土壤有效氮显着正相关，但与SBD呈负相关。这表明，植被与土壤理化特性之间复杂的相互作用调节着草原的恢复过程。一旦排除了放牧干扰，这个降雨丰富的地区退化的高山草甸可以迅速恢复。该研究可以为青藏高原高寒草甸的恢复和可持续管理提供技术支持。一旦排除了放牧干扰，这个降雨丰富的地区退化的高山草甸可以迅速恢复。该研究可以为青藏高原高寒草甸的恢复和可持续管理提供技术支持。一旦排除了放牧干扰，这个降雨丰富的地区退化的高山草甸可以迅速恢复。该研究可以为青藏高原高寒草甸的恢复和可持续管理提供技术支持。
