摘要
2011年11月至2012年1月,采用样点法调查了柳州城市绿地7种类型微栖息地中的鸟类种类和数量,共记录到鸟类75种,隶属11目34科。研究发现,阔叶林的鸟类物种数、密度、多样性指数均最高,针阔混交林的鸟类群落均匀度最好,针叶林的鸟类群落优势度最高。分析认为,微栖息地的食物资源及其复杂性、微栖息地类型的组合是影响城市园林鸟类群落结构的重要因素。
The species and distribution of the birds in 7 microhabitats of Liuzhou urban landscape were surveyed from November 2011 to January 2012 by using point count method.A total of 75 species were recorded,which belonged to 11 orders and 34 families.The results showed that the species number,density,and the diversity index of the avian in broad-leaved forest were the highest.The species evenness index of the avian in mixed wood was the best.And the coniferous forest had the highest species domination index.It suggested that the food resources and its complexity in microhabitat,and the distribution of microhabitat were the important factors to avian community of urban landscape.
