神农架国家级自然保护区夏季鸟类群落多样性

Diversity of Bird Communities in summer in Shennongjia National Nature Reserve

2011年6月至2012年8月,采用样线法对神农架夏季鸟类资源进行了调查。共记录到鸟类140种,隶属于13目38科,占湖北省鸟类总数521种的26.87%。其中国家一级保护鸟类2种,国家二级保护鸟类14种,湖北省保护鸟类28种,中国特有种鸟类14种。该区鸟类群落总体多样性指数(H)为3.846,均匀性指数(J)为0.785,优势度(C)为0.034。β多样性指数分析表明:阔叶林—针阔混交林的鸟类群落相似性系数(S)最高,为0.552 6;阔叶林—水域的鸟类群落相似性系数最低,为0.052 6。区系组成上,东洋种84种(60.0%),古北种42种(30.0%),广布种14种(10.0%),鸟类区系以东洋界成分为主。

The survey of summer birds＇ resources in Shennongjia National Nature Reserve was carried out using line-transect method from July 2011 to July 2013. A total of 140 bird species was recorded,which belonged to 38 families and 13 orders,accounting for 26. 87% of 521 bird species in Hubei Province. Among the bird species recorded,there are 2 species under first-grade state protection,14 species under second-grade state protection,28 species under Hubei province protection and 14 national endemic species. The overall diversity index（ H）,evenness（ J）,and predominant index（ C） of the avian communities were 3. 846,0. 785 and 0. 034 respectively. The similarity index（ S） of broad-leaved forest-theropencedrymion avian communities was the highest（ 0. 5526）,and broad-leaved forest-water area avian communities was the lowest（ 0. 0526）. According to the avifauna,84,42and 14 species were respectively belonged to the Oriental realm,Pala arctic realm and cosmopolitan species,accounting for60. 0%,30. 0% and 10. 0% of the total species. The analysis of bird fauna suggests that the East-Asian Group species is dominant.
