Abstract: Surveys in Tianjin from 1997 to 2000 recorded 107 species of waterbirds. These birds belonged to 7 orders, 14 families and 39 genera, of which migrants accounted for 96.2%. The birds of Anseriformes and Charadriifomes were the dominant species and they comprised 41.1% and 31.1% of the species of the community respectively. Six of the species recorded in Tianjin were national first-grade protected wildlife, including oriental white stork(Ciconia boyciana), black stork(Ciconia nigra), red crowned crane (Grus japonensis), white crane (Grus leucogeranus), great bustard (Otis tarda) and relic gull(Larus relictus). Eight of the recorded species were national second grade protected wildlife, including white naped crane (Grus vipio) , demoiselle crane (Anthropoides virgo), common crane (Grus grus), sea cormorant (Phalacrocorax pelagicus), whooper swan (Cygnus cygnus), whistling swan (C. columbianus), mute swan (C. olor), and white-fronted goose (Anser albifrons). The community diversities of the four main study areas were analyzed by using the G-F index and Shannon-Wiener index. Both Shannon-Wiener index and the G-F index of Beidagang are higher than the other areas, and Beidagang is also a migration stop-over site for many endangered species, so this wetland is a very important resource and should be protected. As the G-F index reflects the diversity of higher classification units of the community, it is a very useful diversity index for the analysis of bird community. The combination of the G-F index and Shannon-Weiner index provides a comprehensive measure of community diversity.
