摘要
1990年5—6月在黑龙江省沾河林业局,通过路线调查法研究了该地区夏季森林鸟类群落的结构,旨在揭示鸟类群落的物种多样性在空间上的变化模式以及它与物种生态位的关系。研究结果表明,该地区不同鸟类群落的物种多样性的排列顺序为针阔混交林>阔叶林>灌丛>针叶林。鸟类群落的物种多样性存在着垂直变化。也随栖位而改变,并且这些变化在各鸟类群落中表现出不同的模式,在不同的鸟类群落中,5种常见鸟类(灰头鹀、大山雀、沼泽山雀、黄腰柳莺、黑眉苇莺)有不同的生态位宽度和生态位重叠。鸟类群落的物种多样性与群落中各物种生态位的平均宽度和重叠存在一定的相关关系。
Studies were conducted in Zhanhe forest region in summer of 1990. Results showed that 4 bird communities were arranged in order of species diversity as follow: Deciduous-coniferous forest>deciduous forest>shrub thorn forest>coniferous forest. The species diversities were changed with the perching heights and the perching positions in different patterns in various bird communities. Five common bird species had different breadths and overlaps of niches in 4 bird communities. A interrelationship existed between the species diversity of bird community and the average breadth and overlap of species niche.
