大盘山国家级自然保护区鸟类群落及其分布特征

Characteristics of bird communities in Dapanshan National Nature Reserve,Zhejiang Province

2005年,在大盘山国家级自然保护区区域范围内,根据自然景观地貌确定一定数量的样线,在每样线上根据不同的生境和海拔高度有针对性地选取一定数量固定半径的调查样点,调查每一样点鸟类的种类和数量以及生境类型和海拔高度。用多元统计分析软件SPSS分析鸟类群落的组成、种类、集群指数和优势种等特征,比较不同季节、生境、海拔与鸟类物种数和个体数量的关系,对不同生境和海拔高度鸟类群落的差异性进行了分析。通过夏季和冬季2次对大盘山鸟类的调查,共目击记录到鸟类64种,其中夏季鸟类51种,冬季鸟类40种。大盘山鸟类群落存在明显的季节差异,群落分布在不同的生境呈现出明显差异,但在不同的海拔高度上差异不明显。夏季繁殖鸟类和作为鸟类重要栖息地的森林植被是大盘山今后鸟类资源保护和管理的重点。

During the summer（1st to 6 th June）and the winter（10 th to 17 th December）in 2005,a survey of the bird communities were conducted in Dapanshan National Nature Reserve by the methods of line transecting and point counting.Along several transecting lines,we chose enough fixed-radius counting points according the altitudes and the habitats.The bird species and quantities,and the habitats each points were recorded.By the multiple statistic analyses of SPSS program,we revealed the characteristics of bird communities in Dapanshan,and compared the differences of bird communities in different habitats and different altitudes.There are 64 bird species in which 51 species were recorded in summer and 40 species in winter.Significant variances（P〈0.05）of bird community characteristics are exits both among different seasons and different habitats,but not in different altitudes.Main protections should be on the summer breeding birds and the forests in the future.
