安徽岳西县位于皖西南边陲的大别山区,山上自然保护区由原始森林和原始次生林构成,田地种植农作物,没有工 业污染,是比较典型的山区自然条件。2009年5月22日～6月10日,利用EC9810臭氧分析仪、OPC-06多道 光学粒子计数器、碳黑度仪等对山区的大气参数进行了测量,得到了山区的地面臭氧,气溶胶粒子昼夜变化及谱 分布的分布特征。与合肥市西郊科学岛的观测结果比较表明: (1)郊区的臭氧浓度明显高于山区; (2)山区和合肥郊 区气溶胶种类不同; (3)郊区气溶胶吸收系数明显比山区大,郊区气溶胶吸收系数的波长指数比山区小。

Yuexi County, located in the Dabie Mountain area, is a typical mountain. The ozone analyzer EC9810, multi-channel optical particle counter OPC-06 and instrument of carbon black are used to measure the atmospheric parameters from May 22 to June 10, 2009. The ozone and aerosol size distribution and their daily variation are obtained. Those data are compared with the ones measured at Hefei. The comparison indicates: (1) ozone level in Hefei is significantly higher than that at Changpu Town in Yuexi County; (2) aerosol types are different between Hefei and Changpu; (3) aerosol absorption coefficient is significantly higher in Hefei than that in the mountain, and aerosol absorption wavelength index is smaller in Hefei than that in Changpu.
