Keyword:  鸟类群落多样性指数自然保护区;
Abstract: 2005年7~8月,采用样线法在广西花坪国家级自然保护区对原生林、次生林、农田-经济林三种生境类型的夏季鸟类群落进行调查,以Shannon-wiener指数、Pielou指数、优势度指数、G-F指数分析鸟类的多样性.结果共记录到鸟类66种,隶属7目29科.原生林的鸟类物种数、物种多样性及G-F指数最高,该群落的鸟类在物种和科属水平上拥有最高的多样性,但是个体数量较少.次生林的鸟类群落密度最高,但是数量集中在几种少数优势种上,多样性指数低.农田-经济林的Pielou指数最高,鸟类群落结构合理、分布均匀、多样性高.保持各类生境空间结构和分布格局,提高植物群落的复杂性,对鸟类多样性及其生存和繁衍有着重要影响.
