摘  要：
从2006年9月至2007年8月,对千岛湖的鸟类进行了调查研究,共发现鸟类6 435只,86种,隶属13目32科,其中,国家二级保护物种6种,属古北界的有36种(占41.9%),东洋界39种(占45.3%),广布种11种(占12.8%)。从居留类型看,千岛湖的迁徙鸟较多(46种),留鸟较少(40种),各占总数的53.5%和46.5%。千岛湖拥有优良的自然环境条件,其中,水鸟有28种,林鸟58种,各占32.6%和67.4%。千岛湖鸟类呈周期性波动特征,在10月,丰富度和多样性指数值最高,优势度指数最低,因此,千岛湖鸟类多样性状况以10月(即候鸟迁徙的高峰期)最好,说明千岛湖是候鸟迁移途中的一个重要驿站。千岛湖全部鸟类物种平均密度为20.785只/km2,秋季最高,达到43.40只/km2,种数达到69种;春季最低,仅有9.30只/km2,种数为37种。而且,优势种有5种,占总鸟类物种的5.8%;常见种有17种,占19.8%;少见种有36种,占41.9%;罕见种有28种,占32.5%。说明千岛湖鸟类中,有生存危险的物种百分比较高,需要加强保护与管理。

摘  要：
Investigation on bird diversity in Qiandao Lake,Zhejiang province from September,2006 to August,2007 demonstrated that 6435 birds of 86 species were recorded,belonging to 13 orders and 32 families,among which 6 species are listed in national protected list,category 2.The observed birds in Qiandao Lake are divided into 36 palaearctic,39 oriental and 11 widespread species.Migrants take 53.5%(46 species) of the birds recorded,and the left are residents(40 species,46.5%).28 species are water birds(32.6%) and 58 forest birds(67.4%).Seasonal change of birds demonstrates the highest level of richness and diversity indexes in October,but the lowest dominant index,indicating Qiandao Lake is an important relay station of migrants.The average density of bird is 20.785 individuals/km2 in Qiandao Lake,43.398 individuals/ km2(69 species) in autumn,and only 9.302 individuals/ km2(37 species) in spring.The investigation showed 5 dominant species,about 5.8% of the total birds,17 common species,19.8%,36 infrequent species,41.9%,and 28 rare species,32.5%,indicating conservation and management in Qiandao Lake needs to be strengthened.
