Aerosol light-scattering coefficient at 525 nm(σ_sp) and PM₁₀ concentration were investigated at two meterological stations of North China in 2005. σ_sp at Minqin in Gansu Province had a mean value of 130 Mm^-1, while at Zhangbei station in Hebei Province this value was 116 Mm^-1. The highest seasonal mean σ_sp was encountered in winter at both the stations. Mean σ_sp at Zhangbei and Minqin stations in winter were 301.6 Mm^-1 and 170.9 Mm^-1, repectively. Aerosol light-scattering at Zhangbei station was more significant than at Minqin station. Conversely, PM₁₀ at Zhangbei station had a mean value of 53 μg·m^-3, while at Minqin station this value was 130 μg·m^-3. The largest seasonal mean PM₁₀ was encountered in spring at both the stations. The mean PM₁₀ at Zhangbei and Minqin stations in spring were 82.2 μg·m^-3 and 190.1 μg·m^-3, repectively. PM₁₀ pollultion at Minqin station was more significant than at Zhangbei station. As to the characteristics of mass scattering efficiency(α), α at Zhangbei station had a mean value of 2.4 m²·g^-1, while at Minqin station this value was 1.1 m²·g^-1. Obviously, the characteristics of aerosol properties at two stations were different, which resulted from different types of aerosol dominated at two stations. Zhangbei station is mainly affected by urban polluted aerosol due to its energy stucture and its location near urban polluted belt in East China, however Minqin station is mainly affected by desert aerosol due to its location near two big deserts in North China.
