摘要
城市化进程通常对城市区域原生态系统造成负面影响。城市鸟类物种多样性的恢复研究,作为城市生态修复的一部分,目前成为研究热点,对科学评价城市生态恢复措施具有重要指导意义。我们于2013~2015年,对广州海珠湿地生态修复工程建设的前期、完成期和成效期的鸟类群落组成及多样性变化规律进行了研究,共记录到鸟类77种,隶属于13目31科。对比采取生态修复前后,鸟类种类及种群数量均逐年增加,物种多样性指数上升,但均匀度有所下降;候鸟和水鸟物种数所占比例呈增加趋势。结果表明海珠湿地生态恢复工程对鸟类群落恢复起到了积极作用,海珠湿地已逐渐成为候鸟和水鸟的重要分布区,在候鸟和水鸟的保护上具有重要意义。
Urbanization usually degenerate the ecosystem around the city area. Bird biodiversity restoration, as part of the ecological restoration, has become a hot spot of study, for its applica- tion in eco-restoration evaluation. From 2013 to 2015, along with the ecological restoration process conducted at Haizhou Wetland, Guangzhou, we studied the structure and characteristics of bird communities at the early, middle and post-restoration stages. The results were as follows： 77 species of birds were recorded, representing 13 orders and 31 families. After the implementa- tion of ecological restoration, total bird diversity and population size increased annually, diversity index increased, but evenness index declined. The proportion of migratory birds and waterfowl species numbers increased. Ecological restoration measures had a positive effect on the restora- tion of the bird community at Haizhu wetland. Now Haizhu Wetland has gradually become an im- portant distribution area, and has played an important role in the conservation of these migratory birds and waterfowl.
