摘要
1993～ 1998年夏季间研究了森林 /草原过渡地带鸟类群落结构及与该生境的关系。共记录鸟类 10 3种。该地区不同生境类型鸟类相互渗透 ,鸟类组成混杂 ,4种环境梯度鸟类群落的相似性系数较低 ,鸟类群落结构随环境变化而呈现出明显的水平梯度变化。森林区是鸟类栖息的主要生境 ,由林缘至林内 5 0m和由林缘至草原 3 0m范围内为鸟类的高密度带。鸟类群落结构随森林植被垂直空间层次复杂性的不同而有明显的空间变化 ,群落物种多样性和均匀性具有垂直空间变化。通过聚类分析和主分量分析将鸟类群落划分为 6个垂直空间栖息取食集团 ,各集团根据各自的栖息取食行为格局分割了生境的空间和食物资源 ,集团内部的鸟类则通过更为细致的生态分割和加剧生态位重叠而得以共存。
The bird community structure was studied in forest-steppe transition zone of Saihanba area between 1993 and 1998. 103 bird species were found, the composition of the bird community was very complex. Values of similarity coefficient of bird communities in four habitat stairs were low. The community structure varied with harizontal habitat stairs. The forest is the main habitat of the birds. The density of birds within 50 m from forest edge to forest inside and 30 m from forest to steppe were the highest. The...
