摘　　要：珍稀濒危鸟类-褐马鸡是中国特有的野生鸟类,是国家一级重点保护动物。采用ICP法和原子吸收光谱法对来自芦芽山、庞泉沟国家自然保护区的野生褐马鸡和太原市动物园圈养褐马鸡羽毛中Mo,Zn,Ni,Fe,Mn,Cr,Cu,K,Pb和Cd等10种元素的含量进行了测定,并对这3个不同地理分布区的样品中10种元素的含量进行了比较。结果表明,在所有羽毛样品中Fe元素含量最高,Mo和Cr含量较低,Cd未检出。动物园饲养的褐马鸡羽毛中除K和Cu外,其余八种元素的含量均低于芦芽山和庞泉沟国家自然保护区野生的褐马鸡羽毛中的含量。生境的不同对褐马鸡机体微量元素有一定影响,野生环境更有利于它们的生长发育。Crossoptilon mantchuricum（brown-eared pheasant） is an endemic to northern China and one of the state first-protection animals,which is now confined to scattered localities in Guandi Mountains,Guancen Mountains,Luliang Ranges of western Shanxi,and the mountains of north-western Hebei,western Beijing and central Shaanxi.Its range is fragmented by habitat loss because of human activity and other intervention,and isolated populations are resulting in facing the extinction risk from further forest destroyed and other pressures.The trace elements are very important to the growth and development of brown-eared pheasant,and these elements in the feather are closely correlated to the contents in the organs of the bird.By research on the elements contents in the feather,the authors are able to get more information about the growth,development,reproduction,immunity and metabolism function for this bird.The aim of this study is to try providing scientific basis for further enhancing the protection and the artificial breeding.Ten elements including Mo,Zn,Ni,Fe,Mn,Cr,Cu,K,Pb and Cd were determined in the feather of brown-eared pheasant by ICP and AAS,respectively.For the analysis two samples were from Luya Mountain Natural Reserve and Pangquangou Natural Reserve,and one was from Taiyuan Zoo,Shanxi.The contents of the elements in the feather of wild and captive brown-eared pheasants were compared each other.The results showed that the contents of the eight elements the feather from the Zoo were lower than those from Luya Mountain Natural Reserve and Pangquangou Natural Reserve.Moreover,Fe is the highest among those ten elements,Cd was not found,and Mo and Cr were much lower than the others.It is suggested that varying habitats have obvious effects on the elements contents of wild bird body,and wild habitant is more beneficial to the bird growth and development.Applying the results to wild animal management would be favorable to the protection,reproduction and ex
