【摘要】 2005~2006年,采用固定半径样点法和样线法对锡林河湿地4种生境的鸟类资源进行了调查,共记录到鸟类97种,隶属于12目33科.研究了不同生境类型中鸟类群落的多样性、均匀度、丰富度、优势度及群落间的相似性等特征.结果显示:沼泽区的鸟类群落多样性指数最高,明水区次之,草地最低.沼泽区和明水区鸟类群落间的相似性最高.更多还原

【Abstract】 The surveys on the bird resources were carried out with the methods of sample point and line transect from 2005 to 2006 in four habitats in Xilinhe Wetland of Inner Mongolia,China.A total of 97 bird species belonging to 12 orders,33 families were recorded.The species diversity,evenness,abundance,dominance of bird communities of different habitats and similarity among communities are studied.The results indicate that species diversity indices of bird communities decrease from swamp to water area,and are the lowest in grassland.The similarity between swamp and water area is the highest.更多还原
