摘要：

为获取徐州市郊大气气溶胶污染特征规律，利用地基遥感手段对2013年7月~2014年5月间徐州市郊气溶胶特性参数进行分析，结果揭示：(1)受冬季燃煤供暖和夏季秸秆焚烧等因素影响，气溶胶光学厚度季节特征显著，且月际、日内波动性显著；(2)气溶胶粒子多含水分，干粒子极少，主要为混合型和人为污染型；(3)5月气溶胶以粗粒子为主控粒子，其余月份均以细粒子为主，且气溶胶粒子类型多样，成分复杂；(4)春季粗模态的气溶胶粒子多于细模态粒子，夏季则相反，秋冬季节粗细模态粒子分布相当；另外，观测期间内徐州市郊基本未受沙尘天气干扰，积聚模态下的细粒子对徐州市郊气溶胶高污染的贡献更大。

Abstract:

In order to obtain the characteristics of the aerosol of Xuzhou city, based on CE-318, parameters of the optical characteristics of aerosol in Xuzhou suburb from July, 2013 to May, 2014 were employed for the analysis. The results show that: (1) Influenced by coal heating and straw burning, significant difference exists in each season, month and day. (2) Most aerosol particles contain moisture, which belong to the mixed type and anthropogenic pollution type. There exist few dry particles. (3) Fine particles with complicated composition play a dominant role except for May. (4) There exist more coarse particles in the spring than in the summer, which is equivalent in the autumn and winter. In addition, there exists rare dust weather during the analysis, fine particles make a greater contribution to the air pollution in Xuzhou city.

Key words: aerosol optical depth, Angstrom exponent, size distribution, refractive index, Xuzhou suburb
