摘要: 为揭示干旱荒漠地区植物群落物种多样性与系统发育多样性的海拔分布特征及其维持机制。本研究以霍拉山荒漠灌丛群落为对象,分析植物群落物种多样性与系统发育多样性沿海拔梯度分布特征及其驱动因子。结果表明:随海拔升高,Margalef指数、Simpson指数、Shannon-Wiener指数和系统发育多样性指数均呈单峰变化趋势,群落系统发育结构由发散转变为聚集状态。系统发育多样性指数与Margalef指数、Simpson指数、Shannon-Wiener指数呈极显著正相关;净谱系亲缘关系指数与Margalef指数呈显著负相关,与Simpson指数、Pielou指数呈显著正相关;净最近种间亲缘关系指数与Margalef指数呈极显著负相关,与Pielou指数呈显著正相关。土壤含水率、全盐、全氮、速效磷含量是物种多样性和系统发育多样性随海拔梯度变化的重要驱动因子。霍拉山荒漠灌丛群落物种多样性与系统发育多样性紧密相关,土壤因子是影响其沿海拔梯度变化的重要因素。

Abstract: In order to reveal the altitudinal distribution characteristics and maintenance mechanisms of species diversity and phylogenetic diversity of plant communities in arid desert areas. In this study, we analyzed the distribution characteristics of species diversity and phylogenetic diversity of plant communities along the altitudinal gradient and their driving factors, taking the desert shrub communities in the Hola Mountains as object. The results showed that the Margalef index, Simpson index, Shannon-Wiener index and phylogenetic diversity index showed a single-peak trend with the increase of altitude, and the community phylogenetic structure changed from divergence to aggregation. The phylogenetic diversity index was positively correlated with the Margalef index, Simpson index and Shannon-Wiener index. The net genealogical relatedness index was negatively correlated with the Margalef index, but positively correlated with the Simpson index and the Pielou index. The net closest interspecific relatedness index was negatively correlated with the Margalef index.The net closest interspecific kinship index was significantly negatively correlated with Margalef index but positively correlated with Pielou index. Soil water content, total salt, total nitrogen, and quick-acting phosphorus content were important drivers of species diversity and phylogenetic diversity with the elevation gradient. Species diversity and phylogenetic diversity of desert scrub communities in the Hola Mountains are closely related, and soil factor is an important factor influencing their changes along the altitudinal gradient.
