Owing to the impact of the western development of China, there have been signs of air pollution over the Qinghai-Tibet Plateau in recent years. However, monitoring data on atmospheric volatile organic compounds (VOCs) are lacking in plateau areas. Here, VOCs concentrations in urban and background areas in North China and the Qinghai-Tibet Plateau were observed from 2012 to 2014 and 2020 to 2022, respectively. Compared to 2012-2014, the concentration of VOCs increased to 2.5 times in urban areas on the Qinghai-Tibet Plateau, which was equivalent to that in North China. Oil, gas, and solvent evaporation caused by a low atmospheric pressure is the primary factor for the increase in VOCs in plateau areas, and weak VOCs degradation is the secondary factor. Hence, we put forward the VOCs control strategies in plateau areas and point out the defects in the current research.
由于中国西部大开发的影响，近年来青藏高原出现了空气污染迹象。然而，高原地区缺乏大气挥发性有机化合物（VOCs）的监测数据。在此，分别于2012年至2014年以及2020年至2022年观测了中国北方和青藏高原城市及背景地区的VOCs浓度。与2012 - 2014年相比，青藏高原城市地区的VOCs浓度增至2.5倍，与中国北方相当。低压导致的油气和溶剂蒸发是高原地区VOCs增加的主要因素，而VOCs降解较弱是次要因素。因此，我们提出了高原地区的VOCs控制策略，并指出了当前研究中的缺陷。
