摘要
2018年3月—2019年2月,采用样线法和网捕法对南昌昌北国际机场鸟类多样性进行调查,共记录鸟类15目40科128种,其中国家Ⅱ级保护鸟类16种。鸟类优势种为丝光椋鸟(Sturnus sericeus)、白头鹎(Pycnonotus sinensis)、麻雀(Passer montanus)和八哥(Acridotheres cristatellus)。区系方面,古北界和广布种最多,各占鸟类物种总数的36.72%,不同季节鸟类区系组成存在较大差异。居留型方面,留鸟最多(47.66%),冬候鸟和夏候鸟次之(分别占21.09%和20.31%),不同季节鸟类居留型组成也存在差异。鸟类多样性方面,春季和秋季鸟类种类最多,这与春秋季节的鸟类迁徙有关。春季鸟类多样性指数最高,是由于春季记录到最少的鸟类个体数所致。不同季节鸟类优势种组成也存在较大差异,这可能是鸟类生态位差异及食物资源变化所致。最后,根据鸟类多样性季节性变化,分析了每个季节重点防范鸟种,并提出了针对性防范措施。
Bird diversity at Nanchang Changbei International Airport was investigated by survey of line transects and mist-net capture and release from March 2018 to February 2019.We recorded 128 species of 40 families and 15 orders.Of the 128 species,16 were listed as second category nationally protected birds.Silky starling(Sturnus sericeus),Chinese bulbul(Pycnonotus sinensis),tree sparrow(Passer montanus)and crested myna(Acridotheres cristatellus)were the dominant bird species.Palearctic and globally widespread species dominated,accounting for 37% of total bird counts,respectively.Residence status varied seasonally.Resident species dominated on an annual basis(48%),followed by winter visitor(21%)and summer breeder(20%).Species richness also varied seasonally.Most bird species were recorded in spring and autumn,which was related to bird annual migration.Diversity was greatest during spring,when lowest numbers of individual birds were recorded.Dominant species also varied seasonally,possibly due to differences in ecological niches and changes in food resources during different seasons.We offer recommendations for species of conservation focus during different seasons and for conservation measures to be based on seasonal changes in bird biodiversity.
