南昌市昌东地区鸟类多样性初步调查

Preliminary Investigation on the Bird Diversity in the Nanchang Suburb

2006年7月至2007年9月,对南昌市昌东地区鸟类多样性进行了初步调查,共记录鸟类48种。其中,留鸟26种,冬候鸟11种,夏候鸟8种,旅鸟3种。在鸟类区系类型上,东洋界鸟类22种,古北界鸟类12种,广布种13种,不确定种1种,结果表明区系类型有东洋界和古北界混杂的现象。校园鸟类仅18种,农田最多,为31种,村庄和湿地分别为25和14种。这种差异主要根源于不同生境的微生境多样性的差异。

The bird diversity was investigated in the Nanchang suburb from July 2006 to September 2007. There were a total of 48 species including 26 residents, 11 winter migrants, 8 summer migrants and 3 travelers. For the avifauna,there were 22 Oriental, 12 Palaearctic and 13 widespread elements indicating that the birds were the mixed one of Oriental and Palaearctic elements. Only 18 bird species were recorded in the campus. On the other hand ,31 bird species were recorded in the cultivation. And 25 and 14 bird species were also recorded in village and wetland respectively. These differences in the bird composition between various habitats may be explained by the differences of micro -habitat diversity in these areas.
