摘　　要：采用直接法测试最大摄氧量(Vo_2max)评价心肺功能,用WHO—NCTB评价作业工效。结果表明:移居者空运进入3680m高原后,早期体力下降明显,Vo_2max下降23％,经7～15月适应后,体力可逐步恢复,达到稳定,但Vo_2max仍比平原值低7.97％。4350m移居者各项指标均较3680m移居者低,7月后已达稳定,但Vo_2max比平原下降21％。低氧时3689m移居者作业工效的影响,表现在反应速度变慢,工效下降,而4350m移居者已开始累及记忆功能,提示低氧的蓄积效应。It was reported that the examination of the Vo_2max with the grade method to determine their cardiopulmonary function and WHO—NCTB to evaluate their working efficiency. The results showed that the physical capacity decreased at first stay after the migrators had arrived at 3 680m altitude and Vo_2max did 23％. After 7～15 months rested,the capacity recovered slowly and became steady. But their Vo_2max was still 7.97％ lower than that of in the plain. The every indexes of the migrators in 4 350m altitude were lower than those in 3 680m and became steady after 7 months,but their Vo_2max decreased 21％. The hypocia conducted the working efficiency decreasing and the reactive speed slowing in 3 680m and was dangerous to the memory function which indicated the accumulative effects of the hypocia.
