【摘要】 物种多样性的垂直分布格局及其解释一直以来受到生态学家的关注。本研究利用云南楚雄地区种子植物名录和研究区域内各气象站点的气候数据,结合空间格局和统计分析的方法,探讨了云南楚雄地区种子植物物种多样性的垂直分布格局,并从物种多样性和气候要素的海拔高度格局等方面与独龙江地区进行了比较。结果表明,楚雄地区种子植物的物种丰富度和物种密度均随着海拔高度的升高而先增加,后下降,在中海拔高度区域达到峰值。从低海拔高度到中海拔高度,水分的单调递增格局是导致物种密度沿海拔高度梯度单调增加的重要因素;而从中海拔高度到高海拔高度,温度的递减格局可能是造成物种密度沿海拔高度梯度单调递减的主导因素。独龙江地区与楚雄地区不同的水分条件可能是导致两者物种多样性垂直分布格局不同的重要因素。
【Abstract】 In a long period,vertical pattern of species diversity has always been one of the important themes in the research of ecologist.In this study,the vertical pattern of seed plants in Chuxiong area was examined,and its climatic explanation was proposed.The species richness and density increased first,then decreased,and reached their peak in midelevation, which might be due to increasing precipitation from low-elevation to mid-elevation area and decreasing mean annual temperature from mid-elevation to high-elevation area,respectively.The distinctness between the vertical patterns of seed plants in Chuxiong and that of Drung river area might lie with the distinctly vertical patterns of precipitation.
