摘要
利用便捷式CO2温度监测仪监测了重庆三峡广场商圈不同地点和时间的大气CO2浓度,采用摄像机记录车流量、人流量及天气状况,采用单因素方差分析和Pearson相关性检验法分析了城市商圈大气CO2浓度时空变化特征及其与各影响因素的相关关系。研究表明,车流量和天气状况是影响城市商圈大气CO2浓度的重要因素,人流量对城市商圈大气CO2浓度的影响不明显。
With the portable monitoring equipments, the carbon dioxide concentration, traffic flow, pedestrian flow and weather condition were recorded in the Three Gorges Square, a typical urban business district at the metropolitan area of Chongqing. Statistical analysis including the Pearson correlation test and One - way ANOVA was performed to test the correlationship between the carbon dioxide concentration and the influential factors. The results showed that traffic flow and weather condition were the statistically significant factors affecting carbon dioxide concentration at the urban business district while the influence of pedestrian flow was not significant.
