中文摘要	利用内蒙古锡林浩特和朱日和2005年的PM10质量浓度(M_(PM))和相关气象要素资料,分析了沙地和草地环境下M_(PM)的分布特征,发现M_(PM)受沙尘天气的影响较大,非沙尘日M_(PM)在不同下垫面条件下差别不大.进一步分析发现,气象要素对M_(PM)有较大的影响,在选取相关气象要素参量的基础上,将各参量相乘建立了气象影响指数I_(PM),表示气象条件对M_(PM)的综合作用,经检验发现锡林浩特和朱日和I(PM)值与M(PM)日均值的相关系数都大于0.70,高于M_(PM)与其他单气象要素,月均值的线性相关性更显著.对同一气候带不同下垫面条件下不同季节I_(PM)值与M_(PM)的对比分析发现,气象条件对近地面M_(PM)的影响比下垫面条件更显著.
英文摘要	There is increasing attention focused on the influence of aerosol to the climate change and the environment. What extent and relationship on the meteorological factors to the aerosol mass concentrations (M_(PM)) is a challenging subject. Studying the relationships is beneficial to improve the aerosol model and better understand the climate change. By analyzing the M_(PM) and corresponding meteorological data of Xilinhot and Jurh in 2005, which locate in semi-arid area in Inner Mongolia, representing sandy land and grassland, the results show great influence on M_(PM) from dust events. There are little difference in non-dust events. Further analysis implies there are interaction between the M_(PM) and the meteorological conditions, that is the wind speed and air temperature increase with larger M_(PM), relative humidity, air pressure and visibility decrease with larger M_(PM), respectively. On the base of correlation analysis between the M_(PM) and the meteorological factors, which the wind, air temperature and air pressure are significantly positive correlation and relative humidity is significantly negative correlation with M_(PM), and the climate condition index I_(PM) expression taking account of the above meteorological factors is given as a comprehensive effect on M_(PM). The results show that the correlation coefficient of the two stations between the I_(PM) value and M_(PM) are larger than 0. 70, more significant than only considering single meteorological factor. And it also indicates that there is obvious linear relation between monthly I_(PM) and M_(PM). By analyzing different seasonal correlation relationship of Ipm values and M_(PM), it shows the latter is the main factor influence on M_(PM) between the different underlying surface conditions and meteorological condition.
