四川农业大学雅安校区鸟类群落结构分析

Bird Community Structure in Campus of Sichuan Agricultural University,Yaan

2009年11月至2010年11月,采用样线法对四川农业大学(雅安校区)的鸟类群落多样性进行了调查,共记录鸟类67种,隶属11目35科,在群落组成上雀形目鸟类占73.13%,在居留型上留鸟占64.18%。鸟类多样性夏季高于冬季,且在不同生境间变化明显,水体及周边区域相对较高。另外,通过对[树]麻雀(Passer montanus)等10种校园优势种生态位宽度及生态位重叠指数的测算发现,[树]麻雀、白鹡鸰(Motacilla alba)、白鹭(Egrettagarzetta)具有最大的生态位宽度,大山雀(Parus major)、红头[长尾]山雀(Aegithalos concinnus)、白头鹎(Pycnon-otus sinensis)之间生态位重叠最为明显。

A survey on bird community diversity was carried out in campus of Sichuan Agricultural University,Yaan from November 2009 to November 2010.Sixty-seven species were recorded,among which Passeriformes species accounted for 73.13%,and resident accounted for 64.18%.Bird diversity was higher in summer than in winter,and showed distinct variety in different ecological habitat,especially higher near and around the river.Ten species were dominant in the campus,and the niche breadths in perching sites of Tree Sparrow（Passer montanus）,White Wagtail（Motacilla alba） and Little Egret（Egretta garzetta） were the top three greatest.Besides,the niche overlaps among Great Tit（Parus major）,Black-throated Tit（Aegithalos concinnus） and Light-vented Bulbul（Pycnonotus sinensis） were much greater than that of other species.
