摘要
城市绿地是城市鸟类的主要栖息地和生态避难所,对维持城市鸟类多样性具有重要的意义。为揭示广州城市绿地的鸟类资源现状和时空动态,于2014年10月至2015年9月,采用固定距离样线法,对广州城市7个绿地鸟类群落组成及多样性进行了逐月调查,结果如下:1)共记录鸟类15 347只,隶属14目、36科、92种。其中,国家Ⅱ级重点保护野生动物5种;留鸟65种、冬候鸟29种、夏候鸟9种和旅鸟9种;2)鸟类物种多样性指数海珠湖公园最高,珠江公园最低;丰富度指数大学城湾咀头湿地公园最高,荔湾湖公园和珠江公园最低;3)鸟类物种多样性指数和丰富度指数呈现季节性变化,春季最高,其次秋季,夏季和冬季最低。鸟类物种多样性在时空上具有明显的差异,可能表明了鸟类物种多样性与食物资源、人为干扰程度、生境特点、植被物种丰富度等密切相关。
Urban green space is the main habitat and ecological shelter of birds in the city,and is important to maintenance of urban bird diversity.To reveal the status and spatial and temporal dynamic of birds in Guangzhou city,we used the line transect method to study bird species representationand diversity monthly in seven urban green spaces from October 2014 to September 2015.A total of 15 347 birds were recorded,representing 92 species,36 families,and 14 orders.Among these,three species are listed as national 2nd category protected animals in China.Residents,winter migrants,summer migrants and passage migrants were represented by 65,29,9 and 9species,respectively.Bird species diversity was highest at Haizhu Lake Park and lowest at Pearl River Park.Bay Mouth Wetland Park of Guangzhou Higher Education Mega Center had the highest species richness and Liwanhu Park and Pearl River Park has lowest species richness.The species richness varied seasonally and were highest in spring,followed by autumn,and lowest in summer and winter.Seasonal and spatial variation in bird diversity in urban green space in Guangzhou probably indicated that bird diversity was closely related with food resources,human disturbance,habitat characteristics,vegetation species richness and other factors.
