摘　　要：此研究旨在分析高原地区高速公路周边大气中二氧化氮(NO_(2))污染的时空特征。在监测区域内部署了多个高灵敏度的NO_(2)污染监测传感器节点,以实现对NO_(2)浓度的实时动态采集与监测。此外,还收集了风向、风速、温度等关键气象参数和车流量等交通相关数据。研究结果显示,NO_(2)浓度在昼夜间有显著变化,白天浓度低,夜晚上升。季节性分析表明,春秋季污染水平相对较低,夏冬季较高。这些发现凸显了地形、气候、交通流量等多因素对NO_(2)污染空间分布特征的复杂交互作用。此研究为相关环境管理和政策制定提供了科学依据。The aim of this study is to analyze the spatiotemporal characteristics of nitrogen dioxide(NO_(2))pollution in the atmosphere around highways in high-altitude areas.Multiple highly sensitive NO_(2)pollution monitoring sensor nodes have been deployed within the monitoring area to achieve real-time dynamic collection and monitoring of NO_(2)concentration.In addition,key meteorological parameters such as wind direction,wind speed,temperature,and traffic related data such as traffic flow were also collected.The research results show that there is a significant change in NO_(2)concentration during the day and night,with low concentration during the day and increasing concentration at night.Seasonal analysis shows that pollution levels are relatively low in spring and autumn,and higher in summer and winter.These findings highlight the complex interactive effects of multiple factors such as terrain,climate,and traffic flow on the spatial distribution characteristics of NO_(2)pollution.This study provides a scientific basis for relevant environmental management and policy formulation.
