Abstract

We have analyzed the results of bird counts averaged over the first half of summer (May 16–July 15) in 1996, 2000–2002, 2007, 2008, and 2013 in Eastern Altai. The hierarchical classification of bird population has been compiled on the basis of cluster analysis. Its structure and the main environmental factors that determine the territorial heterogeneity of ornithocomplexes have been identified. It has been shown that their variability in Eastern Altai and the Altai physiographic mountain region is generally similar in structure. The spatial-typological structure of the Eastern Altai bird population is close to a crescent in its configuration.

初夏阿尔泰东部鸟类群落的空间组织

摘要

我们分析了1996年、2000-2002年、2007年、2008年和2013年东阿尔泰地区夏季前半段（5月16日至7月15日）的平均鸟类计数结果。鸟类种群的层次分类是在聚类分析的基础上编制的。其结构和决定鸟复合体地域异质性的主要环境因素已被确定。研究表明，阿尔泰东部和阿尔泰山地貌山区的变异性在结构上总体相似。东阿尔泰鸟类种群的空间类型结构接近新月形。
