镇江市鸟类生物多样性调查与评价

The Investigation and Evaluation of Bird Biodiversity in the Zhenjiang City

对镇江市城市居住区、农田保护区、城市园林、城郊山林和河流湿地等5种生境冬、夏2季鸟类多样性进行了调查研究。结果表明,5种生境夏季鸟类群落的各种指数均呈现不同的变化规律;城市保护区、农田保护区、城市园林鸟类优势种为[树]麻雀;河流湿地和城郊山林鸟类群落冬夏季在物种水平和科属水平上拥有较大的多样性,群落结构最稳定;城市居住区和城市园林鸟类群落冬季的密度较大,同时良好的栖息地对鸟类的生存起着决定性的影响。

In this paper,five habitats(urban residential area,farmland residential area,urban landscape,suburb mountain forest,river wetlands,etc.) for distribution of bird biodiversity in winter and summer were investigated in the city of Zhenjiang.It was found that five habitats for bird communities in winter and summer showed different results.The bird dominant species of urban residential area,farmland residential area and urban landscape was tree sparrow.The species level and families genera of bird communities in winter and summer possessed larger diversity,the community structure were more stable.The density of bird community of urban residential area and urban landscape was larger,good habitat may play a decisive influence on the bird's surviving.
