(龚嘎蓝孜,等.西藏大学学报(自然科学版),2014,29(2):51~55.)随着海拔的增高大气压下降,氧分压也随之下降,对人体各系统功能造成不同影响。藏族经历了长期的自然选择后在形态、机能、代谢、免疫以及基因等方面表现出与平原人群显著不同的特征,并对高原低氧环境形成适应能力。本文通过对不同海拔地区藏族青年血压、血氧饱和度、心率等的检测,旨在了解生活在不同海拔高度高原世居藏族人群的低氧适应机制。作
(Gaga Lanzi, etc. Journal of Tibet University (Natural Science), 2014,29 (2): 51 ~ 55.) As the atmospheric pressure decreases with elevation, the partial pressure of oxygen also decreases, Cause different effects. After experiencing long-term natural selection, the Tibetans have significantly different characteristics from the plain people in terms of morphology, function, metabolism, immunity and genetics, and have formed the adaptability to the plateau low-oxygen environment. In this paper, the detection of blood pressure, blood oxygen saturation and heart rate of Tibetan youth at different altitudes aims at understanding the mechanism of hypoxia adaptation of the Tibetan population living in the plateau at different altitudes.
