青藏高原大气氧分压及游客高原反应风险评价
Assessment of Atmospheric Oxygen Practical Pressure and Plateau Reaction of Tourists in the Qinghai-Tibet Plateau
摘要
Abstract
The Qinghai-Tibet Plateau is an hot tourism destination for ecological and cultural tourists from inland China. However, the special geographical environment of the plateau become a major obstacle to restrict many low-land residents to travel to The Qinghai-Tibet Plateau. This article selects 110 cities in the Qinghai-Tibet Plateau as research objects, conducts comprehensive filed experiments in the perspective of medical geography to analyze the relation of the altitude and 4 kinds of partial oxygen pressures. The research carries on the quantitative method and GIS technique to evaluate the plateau reaction risk of the tourists from low-altitude places. The conclusion shows: (1) With the altitude increasing, the partial oxygen pressure decrease gradually, and the correlation between altitude and oxygen partial pressure is negative. (2) At the same elevation, Atmospheric oxygen partial pressure, respirable oxygen partial pressure, alveolar oxygen partial pressure, and arterial oxygen pressure is line in turn from high to low. It is same to the breathing function of human body oxygen consumption physiological process. (3) As the altitude rises, the plateau reaction risk increases. The relationship curve shows like “5 steps”. (4) From the spatial aspect, the core of each altitude reaction risk level is always to be bigger cities. The results of this paper are helpful to the local governments and low-land tourists to have a deeper understanding of plateau reaction risk and learning how to avoid or manage the risk.关键词
