摘　　要：为了研究西天目山低山地区人类活动对鸟类群落的影响,于2007年7月对该地区两种自然生境(常绿乔木林和灌丛)与两种人工生境(苗圃和公园)中鸟类的种类、数量及鸟类群落的相似性进行比较。结果表明,常绿乔木林与灌丛中的鸟类物种数最多,常绿乔木林中的鸟类密度显著高于灌丛中的鸟类密度。苗圃和公园中鸟类物种数及密度都显著低于常绿乔木林和灌丛。两种人工生境中鸟类群落相似性最高,广性分布物种是这两种生境中鸟类群落的主要组成部分,而狭性分布物种仅在常绿乔木林和灌丛中分布。以上结果表明,人类活动所造成的生境改变对鸟类多样性有不利影响。Bird surveys were conducted in July 2007 in four habitats, including even-green forests, shrubs, nursery and park, at lower mountain regions in West Tianmu Mountain. No significant difference in bird species richness was found between shrubs and evergreen forests, while bird density in evergreen forests was significantly higher than that in shrubs. Bird species richness and density in evergreen forests and shrubs were significantly higher than that in nursery and park.There was high similarity between bird communities in nursery and in park. Widely-distributed species was the main composition of the bird communities in nursery and park, while narrowly-distributed species was only recorded in even-green forests and shrubs. This suggests that habitat change caused by human activities has disadvantageous effect on bird community.
