摘要:

2001年4月在车八岭国家级自然保护区内,通过实地观察并结合保护区有关工作人员近几年的观察,确定海南开鸟(Gorsachius magnificus)栖息活动和觅食活动比较频繁的6个主要地点(包括当地村民曾经捕获该鸟的确切地点),用全球卫星定位系统(GPS)确定各地点的方位,并对各地点的海拔高度、坡度、坡向和植被等进行考察。结果表明,车八岭保护区内海南开鸟主要选择水源丰富,鱼虾充足的小溪流作为觅食地点,栖息地主要分布在海拔600 m以下,栖息地类型主要有常绿落叶混交林、针阔混交林、灌草丛及竹林等。

Abstract:

Six areas of Gorsachius magnificus activity were selected in Chebaling Nature Reserve in April 2001 in terms of on-the-spot observation and information from the reserve staff observation.These areas including the place where the bird was captured by local resident were investigated using GPS in orientation,altitude,grade,slope and vegetation.^G.magnificus mostly chooses the rivulets of abundant water,fishes and shrimps as feeding sites.The habitats of G. magnificus were mainly under elevation of 600 m.The key types of vegetation around the sites were evergreen deciduous mixed forests,coniferous and broadleaves mixed forests,bushwoods and tussocks and bamboo forests.
