| 摘 要： | 采用二氧化碳自动分析仪和气象资料一套监测了淮安市区大气中的CO2,通过分析采集的数据探索CO2浓度和各种气象条件、季节之间的变化规律。结果表明,淮安市大气CO2浓度一年四季都存在明显的日变化,每天CO2浓度最低值均出现在北京时间15:00时前后;大气CO2浓度随季节变化明显,夏季出现最低值,浓度范围为369.0～395.0μmol/mol,最高值多出现在冬季,浓度范围为420～455μmol/mol。其原因与光合作用的强弱、人为因素、风向等有关。

| Abstract: | CO2 autoanalyzer and meteorological information were used to determine one of the main greenhouse gas CO2 around the urban area of Huai'an.Data collected in the lab was analyzed to find the changing rules between CO2 concentrations and various meteorological conditions.The diurnal variation of the atmospheric CO2 at the urban area in Huai'an displayed a very clear cycle throughout the year.Generally,with the lowest value being recorded at about 15:00 local time and the highest in the morning everyday.Furthe... |
