摘要
2002年2月至2003年2月,对天津七里海湿地鸟类资源进行了调查,共记录到鸟类12目、23科、78种,其中古北界40种(51.28%),广布种31(39.74%),东洋界7种(8.97%)。古北界成分处于绝对优势,与七里海地区处在古北界动物地理区划上是一致的。旅鸟43种,夏候鸟23种,冬候鸟4种,留鸟8种,以旅鸟为主,占总数的55.13%,该地区处于南北迁徙的路线上。其次夏候鸟占29.49%,冬候鸟和留鸟各占5.13%和10.26%。优势种为灰椋鸟、麻雀、红嘴鸥和家燕;天鹅、红隼、黄爪隼、白尾鹞等为国家重点保护鸟类。从类群(科种)多样性分析,陆地鸟对该地区鸟类多样性贡献大。由于栖息地破坏及人为干扰等原因,湿地鸟类明显少于天津其它湿地的鸟类。研究表明,在一定时空条件下,地域景观的复杂性决定这一地区的鸟种数量。
The Survey of the fauna composition and group diversity of Qilihai was made from February, 2002 to February, 2003. The results show that 78 species of birds belonging to 23 families and 12 orders have been found. 40 species (51.28%) belong to Palearctis region,30 species(39.74%) belong to cosmopolition, and 7 species(8.97%) belong to the Oriental birds. 23 species(29.49%) are summer birds, 43 species(55.13%) are travelers, 4 species(5.13%)are winter birds, and 8 species(10.26%) are residents. The birds of land have the most important contribution to the group diversity in this area. In the limited time and space, the landscape diversity is the key factor controlling bird species diversity.
