五龙河自然保护区鸟类群落结构特征分析

An Analysis of Structure Feature of Avian Community in Wulonghe Nature Reserve

湖北五龙河自然保护区为暖温带和北亚热带交汇的森林类型保护区，2005年11月-2006年9月对本区的鸟类群落进行了调查，并对其各季节d和B多样性进行了分析。结果表明：本区记录鸟类82种，隶属8目21科。其中冬季26种，春季29种，夏季50种，秋季51种。有留鸟49种、夏候鸟26种、旅鸟6种、冬候鸟1种。东洋界鸟类40种，古北界鸟类34种，广布种鸟类8种。4个生境鸟种类数在不同季节排序不同，河滩灌木丛生境内鸟类物种多样性最高。在冬、春和秋季，河滩灌木丛和阔叶林生境间相似性最高，夏季以山地灌木林和阔叶林生境相似性最高。保护区内B多样性高，科属间多样性较好。鸟类物种多样性季节变动趋势明显，本区是适宜鸟类的繁殖地，但不适合北方鸟类越冬。

Avian community has been investigated from Nov. of 2005 to Sept. of 2006 in Wulonghe Nature Reserve of Hubei, and its α and β diversity in different seasons and autumn has been also analyzed. The result indicated that： 82 species of avian were recorded in the survey, which belonged to 8 orders, 21 families; 26,29,50 and 51 species were respectively recorded in winter, spring, summer and autumn. 49,26,6, and 1 respectively belong to resident, summer migrant, traveling and winter migrant species. The permutations of the number of avian species are different in every season at four habitats. The level of avian diversity in strand shrubbery is highest. The similarity between strand shrubbery and broadleaf forest is highest in four seasons, and it is highest between upland shrubbery and broadleaf forest in summer. Both 13 and family - genus diversity are nice in the natural reserve. The species diversity of avian changes evidently, so it is fit to reproduction of avian, not to live through the winter of northern avian.
