摘　　要：目的研究不同纬度南极特殊环境对中国考察队员肺功能的影响。方法采用Scope Rotary便携式肺功能仪，对2003年12月-2005年3月期间曾居留的第20次考察队的长城站12名越冬队员，中山站16名越冬队员以及南极内陆冰盖Dome-A的8名度夏队员，进行出发前和返回后的肺功能检测。结果居留南极圈边缘12个月的长城站队员，最大呼吸流速（PEFR）比出发前增加12％（P〈0．05）。居留南极圈内15个月的中山站队员，最高呼吸流速（PEF）比出发前增加9％（P〈0．05）；肺活量（VC）、深吸气量（IC）、用力肺活量（FVC）、1秒用力呼气容积（FEV1）、用力呼气流速25％（FEF25％）和最大肺活量（MBC）较出发前分别增加7％，8％，8％，5％，9％和10％（均P〈0．01）。21次在海拔4000m，夏季平均气温-50℃的Dome—A地区野外考察58d的8名队员，用力肺活量（FVC）较出发前增加10％（P〈0．05）。结论居留南极考察队员的肺功能有一定程度的增强，纬度高肺功能增强更明显。肺功能增强可能是对南极环境的一种适应性反应。Objective Explore the effects of different latitude in extreme environment of the Antarctic on Chinese expeditioners＇ lung function. Methods Lung function was evaluated in 12 wintering expeditioners at ChangCheng station, 16 wintering expeditioners at ZhongShan station of the 20th Antarctic scientific expedition and 8 summering expeditioners at Dome-A zone of the 21th expedition before departure and after return during the period of Dec, 2003-Mar,2005, using the Scope Rotary portable instrument lung function. Results Peak expiratory flow rate （PEFR） of wintering expeditioners of ChangCheng station who stayed in Antarctica for 12 months increased 12% as compared with that before departure （ P 〈 0. 05 ）. Peak expiratory flow rate （PEFR） of wintering expeditioners of ZhongShan station who stayed in Antarctica for 15 months increased 9% （ P 〈 0. 05 ）. Vital capacity （ VC ）, inspiratory capacity （IC）, forced vital capacity （FVC）, forced expiratory volume in one second（ FEV1 ）, 25% forced expiratory flow（ FEF25% ） and maximal breathes capacity （MBC） increased 7%, 8%, 8%, 5% ,9%, 10% （P 〈0. 01） respectively as compared with that before departure . Forced vital capacity （ FVC ） of 8 summering expeditioners at Dome-A of the 21th expedition who stayed at Dome-A zone （4000 meters above sea level, average summer temperature - 50 ℃ ） for 58 days increased 10% （ P 〈 0.05 ） as compared with that before departure. Conclusion Antarctica residence improves expeditioners＇ lung function. The higher of latitude was, the more active lung function was.
