广西山口红树林保护区海陆交错带夏季鸟类多样性调查

2011年6～8月采用样带法对山口地区海陆交错带的5种生境的鸟类多样性及群落相似性进行了研究,共记录到夏季鸟类31种,隶属于9目20科。在5种生境的鸟类群落中,红树林生境的鸟类群落Shannon-Wiener指数最高,农田生境的均匀度指数最高,农田生境和红树林生境的鸟类群落相似性指数最高,为0.759,桉树林生境和农田生境的相似性指数最低,为0.240。同时还对海陆交错带不同生境鸟类群落的多样性和相似性方面的问题进行了讨论。

Diversity of Summer Birds in Marine-terrestrial Interlaced Zone of Shankou District

By the method of line transect,the birds diversity and community similarity of five habitats were studied in marine-terrestrial interlaced zone of Shankou district from June to August in 2011.In total,31 species were recorded,which belong to 11 families and 3 orders.Among the birds community of five habitats,the Shannon-Wiener index of mangrove habitat was the highest,and the farmland habitat presented the biggest Pielou index.The similarity index appeared the maximal value(0.759) in both farmland and mangrove habitats,while that of the lowest(0.240) appeared in the eucalyptus forest habitat and the farmland habitat.At the same time,this article also made the further discussion at issues about diversity and similarity of birds community which lived in different habitats in marine-terrestrial interlaced zone.
