| 英文摘要 | Understanding how grazing influences plant diversity and spatial distribution is essential for evaluating the ecological consequences of grassland restoration, especially in sensitive alpine ecosystems (e.g., Tibetan Plateau). This study assessed the impact of grazing on plant species and functional alpha- and beta-diversity using data from 16 paired grazed and fenced plots across a transect in Tibet. Overall, grazing led to a decline of 9.77 % in species alpha-diversity (Simpson index) and 11.50 % in functional alpha-diversity, while beta-diversity decreased by 4.75 % and 10.03 %, respectively. According to the intermediate disturbance hypothesis, the current grazing intensity in Tibet might not be the optimal level. Spatially, grazing homogenized the latitudes and longitudes patterns of species and functional alpha-diversity. Grazing often promoted alpha-diversity at higher altitudes, but decreased it at lower altitudes. The difference in community composition between fencing and grazing conditions at the same site (/3GF)varied with geographic location. There were differences in the spatial distribution patterns between species /3GF and functional /3GF, likely due to differing dominant factors. Therefore, fencing may be less effective in preserving biodiversity at relatively high elevations, but it can still be a feasible method at relatively low elevations. Functional diversity and beta-diversity may be more sensitive than species diversity and alpha-diversity, respectively, indicating more attention should be paid to functional beta-diversity in terms of biodiversity conservation. |
