吉林龙湾保护区夏季森林鸟类资源及多样性

Birds Resource and Diversity in Summer of Jilin Longwan National Nature Reserve

2011—2014年,在吉林龙湾国家级自然保护区开展了夏季森林鸟类多样性调查,共记录鸟类9目25科74种,其中,候鸟6目18科47种,留鸟4目12科25种,旅鸟1目2科2种。鸟类多样性指数分别为4.50±0.08(Shannon-Wiener指数)、0.93±0.02(Simpson指数)、7.05±0.23(E.Pielou指数)、1.37±0.22(Margalef指数)。结果表明:除留鸟外,吉林龙湾国家级自然保护区也是众多候鸟的繁殖地。留鸟和候鸟4年间的多样性、丰富度及均匀度指数均未发现明显的波动,说明当地生境质量及生态资源丰富度相对较稳定。

The survey on diversity of summer forestry birds were carried out in Jilin Longwan National Nature Reserve during 2011-2014.In total,74 speceis of birds(9 orders and 25 families)were recorded,including 47 species(6 orders and 18 families)of migrants,25 species(4 orders and 12 families)of residents and 2 species(1 order and 2 families)of residents.The species diversity indexes were:4.50±0.08(Shannon-Wiener index),0.93±0.02(Simpson’s index),7.05±0.23(E.Pielou index),1.37±0.22(Margalef index).The results showed that in addition to the residents,Jilin Longwan National Nature Reserve was also the breeding habitat for many summer migratory birds.The diversity,richness and eveness of both migrants and residents did not fluctuate sharply among the four years,suggesting that the quality of habitat and availability of the local ecological resources might be relatively stable.
