中文摘要	生物多样性的大尺度空间分布格局及其形成机制一直是生态学和生物地理学的核心内容。黄河流域是我国重要的生态屏障,明确该区域动植物多样性分布格局及其影响因素,对我国黄河流域生态保护和高质量发展具有重要意义。本研究通过收集黄河流域被子植物和陆栖脊椎动物分布数据,结合气候、环境异质性和人类活动等信息,探讨了黄河流域被子植物和陆栖脊椎动物物种丰富度格局及其主要影响因素。结果表明,黄河流域被子植物和陆栖脊椎动物物种丰富度在区域尺度具有相似的分布格局:南部山地动植物物种丰富度最高,而东部高寒区和北部干旱区物种丰富度最低。回归树模型表明,冠层高度范围和净初级生产力范围分别是黄河流域被子植物和陆栖脊椎动物物种丰富度最重要的预测因子;当移除空间自相关影响后,环境异质性和气候因子依然对区域尺度的动植物物种丰富度具有较高且相似的解释度。表明环境异质性和气候共同决定了黄河流域被子植物和陆栖脊椎动物物种丰富度格局,而人类使用土地面积并不是影响黄河流域动植物物种丰富度格局的主要因子。因此,在未来的研究中若针对不同区域筛选出更精准的环境驱动因子或选用更多不同类别的环境异质性因子进行分析,将有助于更深入理解物种多样性格局的成因。
英文摘要	Large-scale spatial distribution patterns of biodiversity and understanding the mechanisms that form these patterns are core questions for the fields of ecology and biogeography. The Yellow River basin is an important ecological barrier in China. Therefore, understanding the distribution patterns of plant and animal richness and what influences these patterns for is important for the ecological conservation and high-quality development of the Yellow River basin. Here, we used collected data for several variables (species spatial distribution, climate, environmental heterogeneity, and human activity) to explore the spatial distribution patterns of species richness and their main influencing factors for angiosperms and terrestrial vertebrates in the Yellow River basin. We found that the species richness for angiosperms and terrestrial vertebrates had similar distribution patterns at regional scale. Species richness was highest in the southern mountain region and lowest in the eastern alpine region and the northern arid region. Tree regression models showed that the canopy height range was the most important predictor for angiosperm species richness and net primary productivity range was the most important predictor for terrestrial vertebrate species richness. When the spatial autocorrelation was removed, environmental heterogeneity and climatic factors still had important and similar explanations for species richness at regional scale. The results indicate that species richness is determined by environmental heterogeneity and climate. Human activity was not a main influencing factor for species richness pattern. For future research, choosing more accurate environmental driving factors for different regions or selecting different types of environmental heterogeneity factors for analyses will help with understanding the causes of species diversity patterns more deeply.
