【摘要】 塞罕坝人工针叶林鸟类群落组成季节间差异显著(Ps<40%),不同年份相同季节间相似性系数较高(Ps>85%);三个鸟类等级(最重要的鸟类、比较重要的鸟类、较不重要的鸟类)存在明显的季节性差异(Ps<40%).夏季鸟类以候鸟(65%)为主,冬季以留鸟(66.7%)为主.夏候鸟的数量明显高于冬候鸟,多数留鸟在夏季出现数量高峰.候鸟的大量涌入使夏季鸟类群落具有较高的H、PIE值,而冬季E值较高.在三种鸟类捕食集团中,夏季肉食性鸟类(55%)>杂食性鸟类(42.5%)>植食性鸟类(2.5%);冬季杂食性鸟类(55.6%)>植食性鸟类(22.2%)、肉食性鸟类(22.2%).更多还原

【Abstract】 The bird community of Saihanba man-made coniferous forest was made up of 48 species, under 20 families 8 orders, 40 bird species were found in summer, 18 bird species were found in winter. The species, number, species diversity, equitability, PIE and constitution of three guilds had large changes in different seasons,but had small changes in the same seasons in different years. The major reasons of causing seasonal difference were analysed and discussed.更多还原
