高原地区有独特的气候特点,主要是大气压和空气中氧分压低、寒冷、干燥、紫外线幅射强等。生活在高原的人,机体必然要发生一系列变化来适应高原环境。机体的这些变化对适应高原是必要的,但可能对人体带来一些不利影响。高原对人体产生不利影响的轻重,一方面与居住地海拔高度密切相关,而另一方面在很大程度上又取决于个体的反应性。也就是说在同一海拔高度,有的人表现为良好适应,而部分 Plateau region has a unique climate characteristics, mainly atmospheric pressure and air partial pressure of oxygen, cold, dry, strong ultraviolet radiation. People living in the plateau, the body will inevitably undergo a series of changes to adapt to the plateau environment. These changes in the body are necessary to adapt to the plateau, but may have some adverse effects on the human body. The severity of the adverse impact of the plateau on the human body is closely related, on the one hand, to the altitude of the place of residence, and on the other hand to a large extent on the individual’s responsiveness. That is to say at the same altitude, some people showed good adaptation, and part
