摘　　要：为了解中国西部上游区域一氧化碳变化特征及影响因素,利用SPSS软件进行统计分析阿克达拉区域大气本底站一氧化碳2012年1月1日~2018年3月31日每1分钟观测1次的资料和基本气象站同期逐日气象资料,研究分析一氧化碳质量浓度变化特征以及其主要气象要素相关关系。结果表示:阿克达拉一氧化碳质量浓度年变化为下降趋势,并存在明显的季节变化;其月变化呈U型分布,峰谷值出现时间与北半球大气本底站略有差异;没有明显的日变化,与北方城市日变化存在显著差异;单一气象要素对阿克达拉长序列的CO质量浓度的变化有较明显的影响,在不同季节尺度下,阿克达拉CO浓度与主要气象要素的相关关系存在明显的差异性,同时发现我国西部上游大气中的CO变化特征与东部地区和其他大气本底站差异明显。In order to understand the variation characteristics and influencing factors of carbon monoxide in the upper reaches of Western China,SPSS software was used to analyze the data of carbon monoxide observed every minute from January 1,2012 to March 31,2018 at the atmospheric background station in a Akdala region and the daily meteorological data of the basic meteorological station in the same period.The change characteristics of carbon monoxide mass concentration and the correlation of its main meteorological elements were studied.The results show that the annual variation of carbon monoxide concentration in Akdala is a downward trend,with obvious seasonal variation.The monthly variation shows a U-shaped distribution,and the time of peak and valley values is slightly different from the atmospheric background stations in the northern hemisphere;there is no obvious diurnal variation,which is significantly different from the diurnal variation of northern cities;the single meteorological element has a significant effect on the variation of carbon monoxide concentration in Akdala long series,it is found that the variation characteristics of CO in the upper reaches of Western China are significantly different from those in eastern China and other atmospheric background stations.
