乌鲁木齐地区三种不同景观鸟类群落结构初报

The Preliminary Report on the Structure of Bird Communities in the Three Different Landscape in Urumqi,Xinjiang

作者于1994年3－6月在乌鲁木齐地区，对三种不同景观的鸟类群落进行了调查，可划分为3类群落：干旱荒漠为均百灵＋沙群落（群落A）；干旱草原为角百灵＋领岩鹨群落（群落B）；干旱灌丛以云雀＋漠莺＋靴篱莺群落（群落C）。群落的物种多样性以群落C最高（1.8867），次为群落B（1.8837），群落A的多样性最低（1.5212）。种的多样性与生态环境的差异有关。

Investigations on bird community in three different landscape in Urumqi were carried out from Marcll to June 1994. three commtlnities were classIfied as follows.A, Arid desert: Evomophila alpestris + Denanthe isabellina community; B, Arid grassland: Eramophila alpestris + Prunella collaris community; C, Arid shrub: Alauda arvensis + Sylvia nana + Hippolais caligata community. Species diversity indexes of different communities are different .The highest indexes has been found ir community C (1. 8867 ), the next is community B (1. 8837) and the lowert in community A (1. 5212). The indexes are related to the variation of the ecologicol environment.
