海拔高度越高,气压越低,大气中氧分压也越低。在高原地区,缺氧是影响体健康的主要环境因素。在自然条件下,它往往和低温、干燥等其它环境因素起联合作用。高原缺氧可以引起不同类型的“高原适应不全症”。特别是由平原地区初进高原者,往往会出现“高原反应”,尤以“急性高原反应”较为常见。而高原缺氧可引起食欲减 The higher the altitude, the lower the pressure, the lower the partial pressure of oxygen in the atmosphere. In the plateau area, hypoxia is the main environmental factor affecting the body health. Under natural conditions, it tends to combine with other environmental factors such as low temperature and drying. Plateau hypoxia can cause different types of “altitude sickness.” Especially from the plain areas into the plateau, often appear “plateau response”, especially “acute altitude sickness” is more common. High altitude hypoxia can cause loss of appetite
