| 摘 要： | 通过对北京地区CH4和CO2浓度日变化将近一年的连续监测和数据分析,发现它们日变化从总体上来看具有较强的规律性,CO2的日变化有明显的双峰结构,而CH4则是单峰的结构。化石燃料的燃烧,对CO2日变化峰值出现的时间有着明显的影响,且CH4和CO2的日变化具有较好的相关性。源汇强度的变化和昼夜气象因素的周期变化,是两种温室气体形成稳定日变化形式的主要因子。

| Abstract: | One year continuous measurements on methane and carbon dioxide were carried out in Beijing.Their diurnal variation and relationship are studied in detail.Analyzing results indicate that diurnal variation of carbon dioxide has a pattern with two peaks,while methane's diurnal variation with one peak.Statistical analysis also shows that correlation of this two greenhouse gases' diurnal variation is highly significant.The pattern of these two greenhouse gases' diurnal variation can be attributed to periodical variation of daily meteorological factor and their source-sink structure. |
