摘要
山口红树林繁殖鸟类群落的组成种有 32种 ,其中水鸟仅占 1/ 3,非水鸟占 2 / 3。对 8片相互隔离的红树林研究分析表明 ,红树林的物理结构对鸟类群落的结构有重要影响 ,叶层高度多样性 (FH D)与鸟种多样性 (BSD)显著相关 ,红树林的结构越复杂 ,鸟类的多样性越高。与边缘有关的非水鸟有 1/ 4可进入 10 0 m以内的红树林深处 ,边缘效应对红树林片断的影响不可低估。
The breeding bird community in mangroves of Shankou Guangxi,China consists of 32 bird species, among them only 11 species are water birds.The bird communities in eight mangrove forest which are separated each other have been studied. The results indicate that the bird community structure is related to the physical structure of the mangroves, and foliage height diversity(FHD) of the mangroves is closely related to bird species diversity(BSD). Higher FHD implies higher structure diversity in the forest. The more complex structure of the mangroves, the higher the bird diversity is. More than a quarter of the non waterbird species can enter the mangroves over 100 m. The edge effects on the mangroves flagments may be serious.
