内蒙古桦木沟自然保护区夏季鸟类物种多样性调查

为了解鸟类多样性现状,制定科学有效的栖息地保护管理对策,于2006年5～7月利用样线法对内蒙古桦木沟自然保护区鸟类物种多样性进行了调查,并分析了群落结构。结果显示,保护区内有17目44科127种鸟类,其中有国家Ⅰ级重点保护鸟类1种,国家Ⅱ级重点保护鸟类14种。居留型组成为90种夏候鸟、27种留鸟、10种旅鸟。不同生境类型中的鸟类群落多样性指数以草原湿地最高,均匀性指数以林地和疏林较高。提出保护区在制定鸟类多样性保护对策时应全面考虑各类栖息地的生态作用。

Field Survey on Bird Species Diversity at Huamugou Nature Reserve, Inner Mongolia in the Summer 2006

Aimed at understanding bird diversity status and setting for a reasonably habitat management strategy at Huamugou Nature Reserve,Inner Mongolia,a field survey on bird species diversity was conducted at fixed transect lines in the summer from May to July of 2006.Totally 127 bird species were recorded which belong to 44 families and 17 orders.Among them 1 species is listed as Rank I species in the National Protected Species and 14 birds are Rank II species respectively.90 species are breeder in the study area,27 species are residents,10 species are migrants.Habitat of grassland and marsh had a highest species diversity index;however,the evenness indexes were higher at woodlands than any other habitat.Results of the field survey would be used as important basic data to make habitat management plan for the conservation of the birds species and community diversity for the nature reserve authority.
