英文摘要The biogeographic patterns and its drivers of plant diversity across drylands have been well documented, while the associated difference in the determinants of plant beta-diversity between different growth forms remain unclear. Here, we selected 68 plots from a typical dryland region of Northwest China to explore how and to what extent different environmental and spatial factors influence plant beta-diversity of different growth forms. The results showed that environmental and spatial factors were significantly correlated with whole community, shrub and herb beta-diversity (P < 0.001), and the combinations of soil, climate, topography, and spatial factors explained approximately 24, 10, and 20% of the variation in whole community, shrub and herb beta-diversity, indicating that niche and neutral processes work together to regulate plant beta-diversity in drylands of Northwest China. However, the relative contribution of environmental filtering and spatial processes varid between shrub and herb layers, where shrub beta-diversity was predominantly determined by spatial processes, but herb beta-diversity was largely determined by environmental filtering. Taken together, these findings provide an important empirical evidence that niche processes may not always be dominant processes of community assembly, even in harsh environments of drylands. Future research that focuses on the comparisons among different plant growth forms would likely shed new insights into mechanisms of community assembly under climate change. (C) 2021 The Author(s).
