摘要
2002年4月～2003年6月,利用样线法对九寨沟自然保护区的鸟类物种多样性进行了调查,并分析了群落结构.调查记录到鸟类172种,结合历史文献可知,保护区内有鸟类14目43科223种,其中国家Ⅰ级重点保护鸟类4种,国家Ⅱ级重点保护鸟类23种,中国特有种17种.居留型组成为夏候鸟63种、冬候鸟14种、留鸟128种和旅鸟18种.鸟类群落多样性指数以针阔叶混交林最高(3.99),落叶阔叶林的最低(1.79);均匀度指数以水域生境的最高(0.87),村落生境的最低(0.61).各生境鸟类群落结构的相似性都很低(<60%),具有明显的差异.
According to the investigations of species diversity of birds in the Jiuzhaigou National Nature Reserve of Sichuan, China from April 2002 to June 2003, 223 bird species were totally recorded, belonging to 43 families and 14 orders. Among them 4 species are the protected birds under national grade I, 23 birds under national grade II, 17 endemic to China. There were 63 summer migrants, 14 winter migrants, 128 residents and 18 passing migrants in the study area. The highest diversity index of birds （3.99） was found in broad-leaved forest, while the lowest （1.79） in deciduous broad-leaved forest. The evenness index （0.87） was highest in waters habitats, while it was lowest （0.61） in the habitats around villages. The community structure of birds in the water habitats was significantly different from that in other habitats. The similarity index of different communities was very low （less than 60%）, indicating the great and notable biodiversity of birds in the reserve. Tourism has greatly and obviously affected the distribution of birds, and it should be, therefore, controlled. Besides, the environment protection and scientific research should be strengthened in the nature reserve. Tab 2, Ref 16
