摘　　要：为研究城市区域近地面CO_2浓度变化特征,于2016年1月—12月对济南城市大气中CO_2浓度进行了连续观测。结果表明,CO_2具有明显的日变化规律,其中春、夏、秋季存在一峰一谷的现象,而冬季只有一峰。CO_2浓度随季节变化明显,浓度最高值出现在冬季1月份,最低值出现在夏季6月份。CO_2与SO2相关性较高,说明二者都来源于燃煤贡献。CO_2浓度与风速和气温呈负相关关系,而与相对湿度呈正相关关系。Continuous measurement of CO2 at one observation point was carried out in Jinan from January to December 2016 to study the concentration characteristics of CO2. Studies revealed that CO2 exhibited a significant diurnal variation with one peak and one valley in spring, summer and autumn, while the diurnal variation with only one peak in winter. There was an obviously seasonal cycle of CO2, with the maximum in January and the minimum in June. CO2 had a high correlation with SO2, indicating that the main source of CO2 and SO2 emission in this area was coal combustion. Moreover, the CO2 concentration had a negative correlation with wind speed and temperature, and had a positive correlation with humidity.
