摘要
在野外调查的基础上对二滩水库区鸟类多样性进行了测度，结果表明该区鸟类物种多样性丰富，均匀度较好，夏季各生境的ＳｈａｎｎｏｎＷｉｅｎｅｒ指数明显地高于冬季．在同一季节各生境的物种多样性亦有差异．冬季鸟类的β多样性比夏季的高（βｗｓ冬＝１．８８８０＞βｗｓ夏＝１．５６６５）．在相同季节，各生境鸟类的β多样性不同．
Having surveyed in the field and measured the diversity of birds in Ertan Reservoir Area,the authors present the results that the species diversity of birds is abundant,the evenness is good and the Shannon Wiener index(H′) of all kinds of habitats in summer is significantly higher than that in winter.The species diversity in different habitat is different even in the same season.The β diversity of birds in winter is higher than that in summer(β wsw =1.888 0>β wss =1.566 5).In the same season,the β diversity of different habitat is different.
