摘要/Abstract

摘要： 采用Levins生态位宽度及重叠、Shannon-Wiener生态位宽度测度式,定量分析福建三明钩栲群落8个主要伴生树种的生态位宽度、生态位重叠。结果表明,该群落中优势种的生态位宽度值均普遍较大;生态位宽的种群对生态位窄的种群可能有较大的重叠值,反之则低;揭示钩栲的生态位特征及空间分布格局,对今后生产实践具有一定的参考价值。

关键词: 钩栲, 生态位宽度, 生态位重叠

Abstract: Niche breadth and niche overlap of Castanopsis tibetana population with 8 main associated species were quantitatively analyzed. The results show that the niche breadth of dominant species is generally large; the overlap of the wide-niche species to narrow-niche species is greater than that of the narrow-niche species to wide-niche species. The niche characteristics and spatial pattern of Castanopsis tibetana were also discussed.

Key words: Castanopsis tibetana, niche breadth, niche overlap
