武汉桂子山地区几种常见雀形目鸟类种群数量动态

Dynamic Quantity of Birds' Population of Several Common Passeriformes in Guizi Mountain in Wuhan

2005至2007年,在武汉桂子山地区设立5条调查样带,对样带中的灰喜鹊、乌鸫、[树]麻雀、白头鹎4种常见留鸟的种群数量变化进行了调查,并分析校园生态环境对鸟类的影响.结果表明,4种鸟的种群密度均呈上升趋势.各样带由于覆盖的生境类型不同,使得鸟群密度分布不同,并都与其生境丰富度成正相关.

The population changes of 4 common resident species including Cyanopica cyana, Turdus merula mandarinus （blackbird）, sparrow, Pycnonotus sinensis （Chinese Bulbul） had been investigated on 5 sample belts from 2005 to 2007 in Guixi Mountainous area to analyze the impact of the campus ecological environment on the birds. The result revealed that 4 species of birds＇ densities showed the trend of rising. The different habitat types of the sample belts made bird population distribution different, all of which had positive correlation with habitat abundance.
