摘　　要：在江西九连山国家级自然保护区对海南"开+鸟"(Gorsachiusmagnificus)栖息地及活动时间进行了初步考察,结果表明,较高的植被覆盖度(90%以上)和密度有利于海南"开+鸟"的隐蔽,并满足其躲避敌害的要求;海南"开+鸟"对栖息地的坡度选择性不明显,而对坡向的选择性较明显;海南"开+鸟"主要栖息在海拔500m以下,而且多选择溪水流动缓慢、有浅水区或大片沙滩及鱼虾充足的地方作为觅食地;4～6月份海南"开+鸟"活动的频次较高,可能是海南"开+鸟"在九连山的繁殖育雏期。The preliminary investigation about Gorsachius magnificus's habitats and active time carried on in Jiulianshan Nature Reserve in Jiangxi province showed that G.magnificus have the following main features in the habitats. Firstly,the covered area (more than ninety percent) and the density of higher vegetation would enable G.magnificus to take cover and meet their needs to take shelter from the harmful animal. Secondly,it was not obvious that G.magnificus like to live on the slopes of the habitats,while it was obvious that Gorsachius magnificus tend to choose the altitude of the habitats.Thirdly,G.magnificus mainly lived in the habitats under elevation of 500 m,where there were slow streams,shallow waters,great sand beach and plenty of fish and shrimp.Fourthly, G.magnificus were more actively reproductive from April to June,which may be their brooding stage in Jiulianshan Nature Reserve.
