摘　　要：通过2007—07由DMT公司生产的连续流单过饱和度云凝结核计数器所得观测资料及银川市环境监测中心站提供的主要污染物资料,探讨银川市云凝结核(CCN)与主要污染物的关系.分析表明,银川市金凤区、西夏区和兴庆区的日平均CCN浓度存在较大的差异;银川市三区的主要污染物都是可吸入颗粒物(PM10),但是也具有各自的污染特点;CCN浓度的变化与主要污染物浓度的变化密切相关.人类活动在产生大量污染物的同时也影响了CCN的数量,并且通过CCN数量的变化影响云的微物理和辐射特性,并间接影响气候.By analyzing the data which were observed through cloud condensation nuclei counter on July 2007 and pollutant data which were offered by Yinchuan environmental monitoring center,the relationship between CCN and the main pollutants in Yinchuan is discussed.Analysis shows that： Daily average concentration of CCN in Jinfeng,Xixia and Xingqing District of Yinchuan has a big difference;the main pollutant is PM10 in three district of Yinchuan,and has pollution characteristics each other;the change of CCN concentration is relative to the change of major pollutants concentration closely.Pollution from human activities also affects CCN concentration,and then,the change of CCN concentration affects cloud microphysical and radioactive properties,and affects climate indirectly.
