Enclosure is an important measure for restoring degraded grasslands， however， the effects of short-term enclosure on soil quality and multifunctionality of the alpine meadow remain unclear. In this study， we compared the two years effects between enclosure and free grazing （control） on soil physicochemical properties， plant community diversity and soil multifunctionality of a typical alpine meadow in the Xizang Three Parallel Rivers region. The results showed that： （1） short-term fencing significantly affected soil temperature， electrical conductivity and soil organic carbon （F₁=6.945， F₂=5.216， F₃=25.344， P<0.05）. （2） Compared with 2022， plant community diversity （0.966） and the importance value of Poaceae （19.296） were greater than those under fencing in 2023， whereas root-shoot ratio （17.671） and the importance value of Forbrich （8.215） were increased accordingly， as well as Cyperaceae （90.628）. （3） Mantel tests indicated that the correlations between plant diversity and soil physicochemical properties were strengthened in 2023. For grazing control treatment， plant communities were more sensitive to soil changes， while enclosure enhanced correlations between different soil factors. （4） Multifunctionality analysis presented results that ecosystem functions for this alpine meadow were relatively stable under short-term enclosure， whereas greater fluctuations at high-threshold occurred under a control grazing. Overall， the short-term enclosure had limited direct effects on soil physicochemical properties but may indirectly influence soil multifunctionality by regulating plant community structure.
