摘要:

对南极乔治王岛菲尔德斯半岛贼鸥的食性生态进行观测与研究 ,结果表明 ,本区贼鸥的食物结构中 ,自然生态类食物百分组成 ,棕贼鸥 (C .s.lonnbergi)占 63.4% ,灰贼鸥 (C .maccormic ki)占 77.8%。同期 ,取自考察站的人类废弃物中垃圾食物的百分组成分别为 36.6%和 2 2 .3%。贼鸥食性对考察站废弃物有一定的依赖性 ,与本区环境质量下降 ,尤其考察站对废弃物的疏于管理有着直接的关系。由此表明 ,强化南极考察人员环境意识 ,建立封闭式废弃物管理系统 ,对保护南极环境有重要意义

Abstract:

Diet of South Polar and Brown skuas C. maccormicki and C.s.lonnbergi were investigated during the years of 2001—2003 in Fildes Peninsula, King George Island, Antarctica. The results show that percentage components of natural food in their food composition were 63.4% for Brown skua and 77.8% for South Polar skua. Meanwhile the components of the food from station waste were 36.6% and 22.3% respectively. It is clear that foraging of skuas near Great Wall Station was dependent on both of natural resources and station garbage. This is much related to environmental status as well as management of waste material in the stations. Closed treatment technique should be used for station waste, for the benefit of Antarctic environmental protection.
