摘 要 ：在生态位空间分割基础上 ,应用两种不同类型的生态位宽度公式和生态位重叠公式测定了杉阔混交林不同资源空间中主要种群的多维生态位特征。结果表明 :考虑资源利用率与否对生态位宽度的测度有较大影响。杉阔混交林主要种群在不同资源空间中的生态适应性不同。在同一资源空间中 ,种对间生态位宽度与生态位重叠并非成正相关关系。在不同资源空间中 ,杉木与同一其它树种之间的生态位重叠发生变化。生态位重叠与竞争之间关系在很大程度上受种对间的生物学特性的左右。研究杉阔混交林多维生态位特征对混交林营造具有指导作用。

Abstract:Based on the principle of niche space compartmentalization, the characteristics of multi-dimension niche of dominant populations in Chinese fir and broad-leaved mixed forest were studies with the formulas of niche overlap and niche breadth. The results showed that resources availability influenced niche matrices greatly. The adaptability of dominant populations varied in different resources spaces. In the same resources space, there was no positive correlation between niche breadth and niche overlap of a s...
