摘要：湿地生境可为水鸟提供保护场所、生存和繁殖所需要的能量以及种群延续的条件（Fretwell,1972;Heitmeyer,1980;Fredrickson,1981;Krapu,1981）.生境的可利用性、分布和质量会影响越冬期水鸟的集群、活动、能量分配和繁殖过程（Fredrickson et al.,1979;Paulus,1980）,同时会对水鸟的繁殖潜力造成影响（Miline,1976;Ankney,1977）.生境选择通常会使生物分布非随机化,这是自然选择的结果（Southwood,1977;Martin,1998;Clark et al.,1999）.这种非随机化分布方式的产生是由于生物体对环境因子具有选择性,即在相同生境中的随机区域选择位点进行测量,并将它们进行比较的结果（Wilson,1998）.
In February 2012,the foraging habitat selection and distribution of Bar-Headed Goose （Anser indicus） in Caohai National Nature Reserve,were studied by using fixed-spot observations,plots surveys and factor analysis methods.The results showed that the wintering population number of Bar-Headed Goose in Caohai was 1 828,and distributed in all five roosting sites respectively.Human disturbance,escape and food richness,were the main factors influencing their foraging habitat selection in winter.They preferred to choose the sites with high vegetation cover,low vegetation height,far from human disturbance,close from the water,open habitats and lower elevation as their foraging sites.Based on the above habitat characteristics,the Geese selected meadow and farmland as their main foraging sites.
