COMMUNITY ECOLOGY BIRDS ON AREA OF GU TIAN MOUNTAIN ZHEJIANG PROVINCE
浙江古田山自然保护区鸟类群落生态研究

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.
