物种丰富度沿海拔梯度的分布格局成为生物多样性研究的热点。为探讨中尺度区域物种丰富度沿海拔梯度的分布,本文以高黎贡山为研究对象,利用该地区的地方植物志资料,结合通过GIS生成的区域数字高程模型(DEM)数据,分析了该区域全部种子植物和乔木、灌木、草本三种生活型种子植物物种丰富度的垂直分布格局以及物种密度沿海拔梯度的变化特征。结果表明:(1)全部种子植物和不同生活型植物物种丰富度随着海拔的升高呈现先增加后减小的趋势,最大值出现在海拔1500-2000 m的范围;(2)物种密度与海拔也呈现单峰曲线关系; (3)物种丰富度和物种密度分布格局的形成主要受海拔所反映的水、热状况组合以及物种分布的边界影响。

Patterns of species richness along altitudinal gradients have become a focus of ecological research. We explored the patterns of seed plants richness along an altitudinal gradient on Gaoligong Mountains, Southwest China. Information on seed plants and their distribution ranges was collected from Flora of Gaoligong Mountains, and the DEM (Digital Elevation Model) was derived from a topographical map of this region. Using these datasets, altitudinal patterns of richness and species density of all seed plant species and plants of three different life forms (trees, shrubs and herbaceous plants), as well as their relationship with topographic parameters were studied. The results are summarized as follows: (1) the species richness increased rapidly first and then decreased with increasing elevation, peaking at the altitudes of between 1500 m and 2000 m; (2) similar to the altitudinal pattern of species richness, species, genus and family densities (number of taxa per unit area) also showed a humped pattern along the altitudinal gradient. Species density reached a maximum between 1500 m and 2000 m, with an average of 1653 m, while genus and family densities peaked between 900-1500 m, with an average of 1089 m,and (3) energy and moisture represented by elevation, as well as hard boundaries of species distribution were possible factors determining the patterns of species richness and density.
