龙胜里骆林区森林鸟类群落研究

本文对龙胜里骆林区的四种不同植被类型:灌丛—经济林、针叶林、针叶—阔叶混交林和常绿阔叶林中的鸟类群落作了研究,结果表明:阔叶林鸟类群落的鸟种多样性最高(3.14),针叶林鸟类群落的鸟种多样性最低(1.94)。造成这种状况的原因是林型间结构的差异,而不是海拔高度的变化和人类活动的干扰;单纯针叶林生境结构简单,因而栖息于其中的鸟类较少。文中还讨论了鸟类群落与森林虫害的关系。

RESEARCH ON FORESTRY BIRDS COMMUNITY IN LILUO FOREST OF LONG SHENG COUNTY

In this paper, we study birds community from four types of forest with different vegetation cover in Liluo forest of Longsheng county. The result shows that the diversity of bird species which live in groups in the evergreen broad leaf forest is highest (3.14) and the diversity of bird species which live in groups in the coniferous forest is the lowest(1.94). The reason which causes this condition is the drfference between the structure of forests but not the change of elevation and the diturbance of humans'' action. Because of the simple habitat structure of pure coniferous, it is not fit for most birds to live there. The relationship between birds community and forestry injurious insects is also discussed in this paper.
