内蒙古中部地区湿地繁殖鸟类多样性调查

Investigation into Diversity of Breeding Birds in Wetlands in Central Inner Mongolia Autonomous Region

为了掌握内蒙古中部地区湿地繁殖鸟状况,于2013年5-6月,采用固定半径样点法,对内蒙古自治区中部5个地区的湿地繁殖鸟类进行了调查。结果显示,共记录湿地繁殖鸟69种,隶属于13目28科;其中,留鸟9种,夏候鸟60种;古北界鸟59种（占85.5%）,东洋界鸟10种（占14.5%）;在5个调查区中,乌兰察布的湿地的繁殖鸟群落的Shannon-Wiener多样性指数和Pielou均匀度指数最大,红海子湿地的最小;达里诺尔的湿地繁殖鸟群落与乌兰察布的相似性最高。

In order to protect the breeding birds in the wetlands in central Inner Mongolia Autonomous Region,breeding birds in the wetlands were surveyed by fixed radius sample point count methods in 5 habitats of the birds from May to June 2013.The results showed that there were 69 species of breeding birds belonging to 28 families and 13 orders recorded.Among them 9 species were resident birds,others were summer visitors.Considering the avifauna flora,59 species belong to Palearctic Realm,accounting for 85.5% and the other 10 species belong to Oriental Realm,accounting for 14.5% of the total birds in the survey area.In the five surveyed regions,the highest Shannon-Wiener diversity index and Pielou evenness index of bird community were observed in Ulanqab wetlands and the lowest were in Honghaizi wetlands.Similarity peak of bird communities appeared between Dalinuoer and Ulanqab wetlands.
