摘　　要：在渭河平原咸阳地区选取有代表性的 7种生境 ,采用样带法取样 ,选用Shannon Wiener、Pielou指数和多元变量分析法进行鸟类群落结构分析。共发现 6 3种鸟类 ,隶属于 13目 2 9属 4 7科。 7个样区的鸟类组成表明水域面积是影响特定鸟类 (水鸟 )分布的重要因子。α多样性指数和干扰程度呈线性关系 (Y =2 94 5 -0 35 2X)。而中等偏上的均匀度表明不同样区种群的分布较为均匀。进一步对鸟类群落结构进行聚类分析、多维尺度分析以及主分量分析后表明 :按照人为干扰程度的大小将 7个样区划分为 3～ 4个群落组合 ;多维尺度分析的结果比聚类分析的结果更接近实际情况 ;在人为干扰的前提下 ,类似生境 (相同高程或相近水域面积 )鸟类群落的相似性程度并不高。In order to investigate the avifauna and bird community in Weihe Plain and to discuss the similarity between communities in the different habitats and its influencing factors,the bird species and their abundance in seven different sites were studied by line sampling method,Shannon Wiener,Pielou indices and Multivariate analysis.According to the record,there are 63 species in that area,belonging to 13 orders,29 genera and 47 families.Dominant species in different suits showed that water area was the important factor to special bird.Diversity were related to human disturbance ( Y =2 945-0 352 X ).Higher evenness suggested that different communities distributed even,and influenced by water and human disturbance .The results of the Hierarchical Cluster,Principal Components Analysis (PCA) and Multidimensional Scaling (MDS) suggested that all suits could be divided into 3-4 groups by the human disturbance,and the result of the MDS was better than that of the Hierarchical Cluster.Special factor,such as human disturbance,had influenced the bird communitys structure significantly and resulted in dissimilarity between similar habitat.
