物种多样性地理分布格局及其成因是生物地理学和宏观生态学研究的核心问题之一,基于中国13个典型森林生态系统乔木层群落植物的调查数据,分析物种多样性随经纬度的变化规律,探讨物种多样性空间分布格局的影响因素。结果表明: (1) 13个典型森林生态系统的4个物种多样性指数均随经纬度上升而下降,其中物种丰富度变化更为显著,而Shannon-Wiener指数、Simpson指数和Pielou指数随经度上升变化不显著; (2)相关性分析结果显示,物种多样性指数与植物特性、能量和水分因子的单因素相关关系并不一致。其中,物种丰富度、Shannon-Wiener指数和Simpson指数与年均温、最冷月均温、温度年较差和潜在蒸散量的相关...

Large-scale patterns of species diversity are one of the most important and attractive issues of ecology and biogeography. Using the investigation data of tree layers in 13 typical forest ecosystems in China, we explored the geographical patterns and main influencing factors of species diversity in the forest community. Our results indicated that four species diversity indices decreased with an increase in latitude and longitude in the 13 typical forest ecosystems. Species richness, in particular, showed a significant variation along both latit...
