柳州城市公园冬季鸟类食源树种调查研究

Study on Bird-feed Trees in Parks of Liuzhou Urban Area in Winter

2009年11月至2010年1月调查柳州城市公园内利用植物鸟类和现有树种中鸟类食源树种的种类和数量,记录到利用植物的鸟类32种,鸟类食源树种24种,其中利用植物的鸟类多样性与鸟类食源树种物种数之间存在显著正相关关系,据此对城市公园园林建设和管理提出建议。

The species and quantity of the birds with plants as total or part of their foods and the bird-feed trees were investigated in Liuzhou parks from November 2009 to January 2010.A total of 32 birds eating seeds or fruits of plants and 24 bird-feed trees were recorded.The diversity of the birds with plants as food was positively correlated with the species of the bird-feed trees.At last some suggestions about the landscape construction and management of city parks were discussed.
