摘 要：
2007年8月至2009年1月对东洞庭湖湿地鸟类资源进行了为期一年半的野外调查,以研究该保护区鸟类的群落多样性。从物种丰富度指数(S)来看,夏季S稀>S居>S水>S沼*,冬季S水>S沼>S居>S稀;从Shannon-Wie-ner多样性指数(H)来看,夏季H稀>H居>H沼>H水,冬季H水>H沼>H居>H稀;从Pielou均匀性指数(J)来看,夏季J稀>J沼>J水>J居,冬季J沼>J水>J居>J稀。夏季鸟类中对多样性贡献最大的类群是雀形目,冬季鸟类中对多样性贡献最大的是雁形目。水域、芦苇草滩沼泽和居民区生境鸟类群落的物种丰富度指数、Shannon-Wiener多样性指数变化趋势为:S冬>S夏,H冬>H夏;稀树灌丛生境鸟类群落的物种丰富度指数和Shannon-Wiener多样性指数变化趋势为:S冬J冬。
BiM resources of East Dongting Lake wetlands were studied from August 2007 to January 2009. The analysis on communities diversity of birds was carried out. In four habitats, the sequence of species richness index is wood and shrub habitat 〉 neighborhood habitat 〉 water habitat 〉 swamp habitat in summer, water habitat 〉 swamp habitat 〉 neighborhood habitat 〉 wood and shrub habitat in winter. The sequence of diversity index is wood and shrub habitat 〉 neighborhood habitat 〉 swamp habitat 〉 water habitat in summer, water habitat 〉 swamp habitat 〉 neighborhood habitat 〉 wood and shrub habitat in winter. The sequence of evenness index is wood and shrub habitat 〉 swamp habitat 〉 water habitat 〉 neighborhood habitat in summer, swamp habitat 〉 water habitat 〉 neighborhood habitat 〉 wood and shrub habitat in winter. The biggest contribu- tion to bird diversity is Passeriformes in the summer, and Anseriformes in the winter. The variation trend of species richness index and diversity index is winter species 〉 summer species, winter diversity 〉 summer diversity in water habitats, swamp habitat and neighborhood habitat. The variation trend of species richness index is winter species 〈 summer species, winter diversity 〈 summer diversity in wood and shrub habitat. The variation trend of evenness index is summer evenness 〉 winter evenness in four habitats.
