中文摘要 | 内蒙古半干旱草原区大气气溶胶浓度以及散射等特性对生态环境,气候变化与预测研究有重要意义,文利用2009年1~4月在锡林浩特观象台草原站的观测资料,分析了冬,春季背景大气气溶胶质量浓度,黑碳质量浓度,散射系数的分布特征.研究发现,背景天气下,PM10,PM2.5,PM1.0浓度值都较低,平均值分别为22.7,9.5,6.1mug/m3,3种PM浓度值间的相关性不同;黑碳浓度平均值为0.59mug/m3,小粒子中的含量较高,其日分布规律受人类活动影响较大,与各PM浓度分布有较大不同;散射系数平均值为31.2Mm-1,与PM10,PM2.5,PM1.0,黑碳质量浓度都显著相关.三种PM中,PM2.5对散射和吸收的影响最大.风速,相对湿度对不同粒径的PM以及黑碳浓度,散射系数的影响有所不同 |
英文摘要 | The characteristics of atmospheric aerosol over Semiarid typical steppe Area are important to study the climate change such as the concentration, scattering and absorbing characteristics. By analyzing the observing data of aerosol mass concentration, black car mass concentration and the scattering coefficient of 1 ~ 4 month in 2009 of Xilinhot, Inner Monoglia Autonomous Region, the physical characteristics of dust aerosol was discussed. The results show that the mass concentration of PM10,PM2.5 and PM1.0 are low with 22.7mug/m3,9.5mug/m3 and 6.1mug/m3 respectively. The correlation relationships between the three types of PM is difference. The black carbon is mainly being in the small particles with the average value 0.59mug/m3.The daily distribution of black carbon concentration is mainly effected by the human activity which is different with the PM.The mean of scattering coefficient is 31.2Mm-1, with the significant correlation with PM and black carbon. Of the three types of PM, the PM2.5 is the most significant correlation to the scattering and absorbing characteristics. At the last, the wind velocity and the humidity are different influence in PM, scattering and black carbon |
