【摘要】 2007年及2009年3～8月期间,对绿洲城市代表——奎屯市的8类生境(依据其城市功能划分)的鸟类进行了调查。共记录鸟类61种,隶属于9目23科30属。留居型中夏候鸟29种、冬候鸟7种、留鸟24种、旅鸟1种。区系组成:广布型27种、古北型17种、全北型5种、中亚型12种。8类生境的鸟类多样性指数(H’)由大到小依次是:公园>苗圃果园>市区间农田>学校校园>工厂区>交通用地>居民区>商业区。公园的鸟类多样性指数最高,达1.421 2;而商业区的鸟类多样性最低,仅有0.413 7;公园的鸟类均匀度指数最高0.859 7,商业区的鸟类均匀度指数最低,仅0.319 0。以上数据显示:鸟类在城市中的分布极不均匀;在绿洲城市中,区域内鸟类种类数量与其林木覆盖率呈正相关关系。更多还原

【Abstract】 The community component and diversity of birds in eight habitats in Kuitun,an oasis city,war investigated from March to August in 2007 and 2009.Sixty-one species of birds were recorded under 30 genera,23 families,9 orders.Of them,29 species are summer resident,7 winter resident,24 resident and 1 passing by;27 species distributing wide,17 occurring in Palaearctic realm,5 in Holarctic realm,12 in Central-Asia respectively.The value of bird diversity indices is descending in eight habitats in the order of park,nursery orchard,suburb farmland,schoolyard,factory district,traffic area,residential area and commercial district.The diversity index of park is highest(1.421 2) and the index of commercial district is lowest(0.413 7).The evenness index of Park and commercial district were the highest(0.859 7) and the lowest(0.319 0) respectively.The distribution of birds in city was extremely uneven and is closely related to the forest cover rate.更多还原
