东明山森林公园鸟类群落生态

Community ecology of birds in Mount Dongming of Zhejiang

对浙江省杭州市郊东明山森林公园 3种不同生境的鸟类进行了调查。结果表明 ,该公园及周边地区鸟类群落的主要鸟类共计 2 7种 ,其中优势种 5种 ,占 1 8 52 %。根据鸟类生境的分布系数分析 ,广性分布型有 4种 ,占 1 4 81 % ;中性分布型有 2 3种 ,占 85 1 9%。不同生境内鸟类群落的种类数目和群体密度存在着差异 ,各种鸟类分布群在鸟类群落内比例随栖息地结构的不同而不同 ,由于这些不同导致鸟类群落的相应参数的不同。表 4参

A survey of birds was conducted in Mount Dongming,Zhejiang Province.Twenty serven species of bird community were found in this area,of which 5 species(18 52%) were dominant species.According to the distributime coefficient of birds,4 species (14 81%) fell to eurylope distribution pattern,and 23 species(85 19%)were middling distribution pattern.There were differences on the number of species and density of bird community in the different babitats.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.
