摘要
持续而快速的城市化进程正在助长全球生物多样性的丧失,其中鸟类是城市生态系统的重要环节和城市生物多样性保护的重点目标,同时也是研究的热点内容。从城市环境变化压力下,鸟类群落组成与结构、空间分布和繁殖营巢方式的改变分析,重点介绍了支持城市地区鸟类多样性的植物环境因素与影响机制的最新研究成果。结果表明:1)城市中的植被和绿色空间为城市鸟类提供生存空间和食物资源,是城市鸟类最主要的栖息地。2)保留原生乡土植物和大型树木的地区能支持更丰富的鸟类物种。3)植被的结构和盖度对鸟类群落有显著影响。林冠覆盖率增加,复杂的垂直空间和多样的植物种类的组合产生各种不同类型的植物空间和栖息地类型,吸引不同的鸟类物种,相应地也会导致更丰富的鸟类群落。总之,保持和加强城市中植物环境良好和稳定是保护城市生物多样性的有效手段。据此,提出城市环境与鸟类群落关系研究的未来发展方向,指出了其在鸟类多样性保护和城市可持续发展等领域的应用前景。
There are more than half of the world′s human population living in cities.The vast amount of predicted rapid urbanization in the coming years consuming habitats and reducing the possibilities for wildlife to thrive in cities,and is contributing to the loss of global biodiversity.Among them,birds are the most important part of urban ecosystem and a key target for urban biodiversity protection.Besides,it is also a research hotspot.The last 20 years of urban bird ecology research have experienced exponential growth and now enables literature analyses and reviews.Here,we try to roundup these present findings on urban bird communities research from all over the world,overviewing patterns and variation processes on urban bird community,especially the changes in composition and structure,spatial distribution,living habits and the way of breeding and nesting under this continuous and rapid urbanization.To further assess the importance of and contributions provided by urban green space and vegetation to the urban bird community,exploring its affecting mechanisms that support bird diversity in urban areas,we reviewed the published literature for such studies.The results showed that:1)Provision of greenery can ameliorate the hostility of the urban environment for wildlife,as well as provide suitable living space and food resources for urban birds.Green spaces provide the most important habitats for urban birds.2)Not all forms of greening benefit bird communities to the same extent.Compared to those areas that do not pay much attention to native plant protection,areas that retain natural or semi-natural cover and large trees can support richer bird species.3)Structure and coverage of vegetation have significant impacts on bird communities.The increasing canopy coverage,complex vertical structures and many kinds of plant species can produce various types of plant spaces and heterogenetic habitats.The increased plant spaces and habitats can cause changes in bird community composition,a correspondingly increase in species ric
