天童常绿阔叶林中鸟类群落结构的空间生态位分析

在1983年和1984年的繁殖季节,作者对浙江省天童山中常绿阔叶林内的繁殖鸟类作了测定。分析中使用了线路统计方法,并对13种鸟类作了1,285次观察。 作者在野外收集了每一个种在生境利用方面(包括种的垂直分布和水平分布,鸟类栖息的树杆直径)的数据,并在图1、图2和表1中列出了每一个种的分布差异。每一个种在这三个生态位维度上的生态位宽度值也分别列于上述的图表和表格中。由Cody(1974)介绍的方法,作者在表2和图3中制作了群落矩阵和树杈状图。 在文章的最后部分,作者描述了每一鸟类小派的特征,并讨论了制作群落矩阵和树杈状图的意义。

THE NICHE ANALYSIS OF BIRD COMMUNITY IN EVERGREEN BROAD-LEAF FOREST IN TIANTONG MOUNTAIN, ZHEJIANG PROVINCE

During the nesting seasons in 1983 and 1984, the author had examined the breeding bird community of evergreen broad-leaf forest in Mt.Tiantong, Zhejiang Province. The transect count was used and the total of 1,285 bird detections of 13 species were used in this analysis.Field data on habitat utilization for each species (both vertical and horizontal species distributions, the diameters of branches which the bird perched on) were obtained and the distribution differences for each species on three niche dimen...
