赣州市鸟类多样性初步调查

A Preliminary Investigation on the Bird Diversity of Ganzhou City

2012年1月至2015年2月,采用样线法和随机踏查法对赣州市鸟类多样性进行了初步调查,共记录鸟类10目34科77种。其中,大余县记录鸟类58种,高校区记录鸟类29种,公园记录32种。居留型方面,留鸟(68.83%)最多,其次为冬候鸟和夏候鸟(均为14.29%)。区系方面,东洋界鸟类种类最多,占54.55%,其次为广布种鸟类,占24.68%。优势种方面,高校区优势种为[树]麻雀Passerm ontanus和黄腹山雀Parus venustulus,公园优势种为白头鹎Pycnonotus sinensis。两地优势种不同主要是由于公园的人工树林资源较为丰富,适合大量的白头鹎生存。鸟类多样性指数公园高于高校区,其多样性指数分别为4.273和3.705,均匀度指数分别为0.855和0.763。高校区鸟类多样性相对更低的主要原因是高校区鸟类数量更多的集中于优势种上,降低了其鸟类多样性。

From January 2012 to February 2015 ,bird od and random survey in Ganzhou city. A total of 77 recorded. There were 58 species in Dayu County,29 For the residence type, the number of resident birds diversity was investigated by line transect meth- species belonging to 34 families 10 orders were species in Campuses and 32 species in Parks. （68.83%） was the most,followed by wintering birds and summering birds （ 14.29% andl4.29%, respectively）. In term of avifauna, Oriental realm, accounting for 54.55% ,are the most common species ,followed by widespread species （24.68%）. The dominant species in Campuses are Passerm ontanus and Parus venustulus while in Parks are Pycnono- tus sinensis. The difference of dominant species in the two places were mainly due to large tracts of artificial forest in Parks attracting many Pycnonotus sinensis. The bird diversity index and evenness index in Parks are higher than those in Campuses （the former H=4. 273 ,E =0. 855 ;the latter H= 3. 705, E = 0. 763 ）. The direct cause of the low bird diversity in Campuses is the number of birds in Campuses was more concentrated in dominant species.
