| 摘 要： | 沙尘不仅是生态环境恶化的重要标志,也会污染大气环境,影响气象、气候和人体健康。为了探讨沙尘天气对内蒙古草原城市大气环境的影响,综合利用遥感影像与地面观测数据,研究了沙尘天气对锡林郭勒盟草原城市大气环境质量的影响,以期为沙尘天气环境影响评价提供理论依据。研究表明利用MODIS(the moderate resolution imaging spectroradiometer)数据可以实现沙尘活动的遥感监测,结果与基于地面观测发生规律一致;并得到气溶胶自动观测网(aerosol robotic network,AERONET)AOD(aerosol optical depth)产品验证。沙尘天气引起草原城市能见度下降,空气环境质量下降。大气污染主要由颗粒物的增加引起;但伴随沙尘天气的大风使CO、NO_2、SO_2等污染物浓度下降,具有清除人为源所排放污染物作用。

| Abstract: | Dust activity is the symbol of environmental deterioration, and dust pollutes the air, affects meteorology, climate and human health. To find the effects of aeolian dust on urban atmosphere in Inner Mongolia grassland, satellite images and ground observations were used to study the impacts of dusty weather on urban air quality in Xilingol Grassland. The objective is to provide theoretical basis for environmental impact assessment in this region. The results showed that MODIS (the Moderate Resolution Imaging Spectroradiometer) composite images could be used to observe dust activities, because dust emissions identified by remote sensing accorded with ground observations and AERONET (Aerosol Robotic Network) AOD (Aerosol Optical Depth) and products. Dusty weather decreased air quality, resulting in severe air pollution. The air pollution was caused by the increase of particulates (PM10), and strong wind accompanied the dust decreased concentrations of some pollutants including CO, NO2 and SO2. Therefore, while the dust event increased PM10, and the strong wind diluted and carried away some man-made pollutants. |
