浙江古田山自然保护区鸟类群落生态研究

COMMUNITY ECOLOGY BIRDS ON AREA OF GU TIAN MOUNTAIN ZHEJIANG PROVINCE

对古田山地区鸟类进行的调查表明:该地区鸟类群落的主要鸟类共计48种,其中优势种有14种,占29.17％。根据鸟类生境的分布系数分析。中性分布型有(25—100％)28种,占58.33％。不同生境内鸟类群落的种类数目和群体密度存在差异,结构复杂的生境,其鸟类群落由三个分布群组成,如农田村落、农田河滩、混交林和阔叶林;结构简单的生境,如竹林、针叶林和迹地灌丛,其鸟类群落由二个分布群所组成。各种鸟类分布群在鸟类群落内的比例随栖息地结构的变化而改变。由于栖息地结构的变化同样也导致鸟类群落其他参数的变化,如Shannon-Wiener多样性指数、Simpson优势度、种间相遇机率PIE等。

A survey of birds was conducted in Gu Tian Mountain and its adjacent area, Zhejiang Province.48 species of bird community were found in this area, of which 14 species (29.17%) were dominant species and 28 species (58.33%) of the mddling distribution pattern according to the distributive coefficient of birds. There were differences on the number of species and density of bird community in the different habitats.The component species of bird community consists of three avian distribution groups in the complicated habitat, such as cropland with village, cropland with river banks mixed forest of evergreen broad-leaf and coniferous and evergreen broad-leaf forest. However, the component consists of two groups in the simple habitat-bamboo forest,coniferous forest,slash and scrub. The proportion of the avian distribution groups in bird community was changeable as a result of the variation of the habitat structure. The variation of the habitat structure also brought about the changes of the bird community parameters(Shan-non-Wiener index, Simpson index and PIE). In this paper the similarity about the compnent species of bird community between habitats was discussed.
