The community component and diversity of birds in eight habitats in Kuitun, an oasis city, war investigated from March to August in 2007 and 2009.

Of them, 29 species are summer resident, 7 winter resident, 24 resident and 1 passing by; 27 species distributing wide, 17 occurring in Palaearctic realm, 5 in Holarctic realm, 12 in Central-Asia respectively. The value of bird diversity indices is descending in eight habitats in the order of park, nursery orchard, suburb farmland, schoolyard, factory district, traffic area, residential area and commercial district. The diversity index of park is highest (1.421 2) and the index of commercial district is lowest (0.413 7). The evenness index of Park and commercial district were the highest (0.859 7) and the lowest (0.319 0) respectively. The distribution of birds in city was extremely uneven and is closely related to the forest cover rate.
