摘要
2006年采用固定半径样点法和样带法对内蒙古白银库伦遗鸥自然保护区内7种生境的鸟类进行了调查.秋季共记录到鸟类45种,隶属于8目20科.研究了不同生境类型中秋季鸟类群落的多样性、均匀度和优势度等群落特征.调查结果显示:不同生境中的鸟类多样性和优势度差异较大,以湿地中明水水域生境的鸟类多样性指数最高,数量最多.鸟类群落结构主要与环境中的食物资源、隐蔽条件及人为干扰强度有关.
The bird surveys were carried out with the methods of sample point and line transect in 2006 in 7 habitats in Baiyinkulun Nature Reserve of Inner Mongolia, China. In autumn, 45 bird species were recorded totally, which belong to 20 families, 8 orders. Based on the principles of community ecology, we evaluate and discuss structural characteristics of different habitats by means of Shannon - wiener index, species evenness and dominance in autumn bird community. The results indicate that there are different indices in 7 habitats. The diversity index is highest in marsh lakes of wetland area, and the number of birds is the largest too. The avian community structure has certain correlation to food resource, shelter and artificial disturbance intensity.
