| Summary: | 碩士 === 國立臺北科技大學 === 環境規劃與管理研究所 === 94 === Because of the dusting effect from the exposed area increasing particles in the air, this research aimed at the characteristics of PM10 emission and used the measure of seeding to prevent the particle pollution in the air from the exposed area. For the discussion of the characteristics of PM10 emission, this research utilized the concept of law of Overall Mass Balance (OMB) and measured factors of PM10 emission in the thirteen sampling exposed areas to the extent of 292.3~308.5K temperature, wind velocity 0.5~3.6m/s and humidity 35~78%. The results showed that the average amount of PM10 emission was 40 g/m2/month, the emission increased 1.8 times when the silt content of topsoil doubled, the emission increased 80% when the average wind velocity increased from 1 m/s to 3 m/s, the emission reduced 42% when the topsoil moisture content increased from 2.0% to 4.0%, and the prevention efficiency of emission was 47.5% when the vegetation ratio of seeding reached 51.4%.
