| 英文摘要 | The Qinghai-Tibet Plateau (QTP) harbours the largest wetland complex in China, with a relatively high diversity of wetland plants. While there has been extensive research on the a-diversity of various plant groups in the QTP, the study of 8-diversity specifically in wetland plants has been limited. In this study, we quantified the geographic pattern of wetland plant 8-diversity from three dimensions: taxonomic, phylogenetic, and functional. We assessed the relative importance of geographic distance, climatic distance, environmental distance and topographic distance on the pattern of 8-diversity. The results indicate a high consistency in the geographic pattern of wetland plant 8-diversity across the three dimensions. 8-diversity is high in the mountainous regions at the edge of the plateau and relatively low in the plateau platform. The turnover component contributes more to taxonomic 8-diversity than nestedness, whereas the opposite is true for phylogenetic and functional 8-diversity. Furthermore, taxonomic 8-diversity is higher than phylogenetic and functional 8-diversity. The geographic patterns of taxonomic, phylogenetic and functional diversity of wetland plants in the QTP are jointly influenced by environmental filtering and dispersal limitation. Climatic variables (temperature seasonality, annual precipitation, precipitation seasonality and annual mean temperature) and topographic variables (elevation variation coefficient, elevation and slope) were identified as the main factors influencing wetland plant 8-diversity in the QTP. Overall, this study contributes to elucidating the evolutionary history and formation mechanisms of wetland plant communities in the QTP, and reveals the large-scale patterns of wetland plant diversity. |
