Air Anion Concentration: Difference in Different Underlying Surfaces in Mohe

doi:10.11924/j.issn.1000-6850.casb16120071

Abstract

Abstract: To study whether there is a significant difference in the concentration of air anion in different underlying surfaces, we comparatively analyzed 6 different underlying surfaces in the Arctic village of Mohe including coniferous forest (sylvestris), broad-leaved forest (birch), coniferous and broad-leaved mixed forest (camphor mixed), wetlands, grassland and open space. Each observation area was selected for each underlying surface to measure the air anion concentration, a total of 6 observation areas. In the local observation air anion concentration data, outliers were filtered and removed. We used SPSS to analyze the difference of air anion concentration in different underlying surfaces. The results showed that: there were significant differences in air anion concentration in 6 different underlying surfaces, and anion concentration from high to low were coniferous forest, coniferous and broad-leaved mixed forest, broad-leaved forest, wetlands, grassland and open space. The air quality of coniferous forest, coniferous and broad-leaved mixed forest reached the highest level of cleanliness, and that of wetland and broad-leaved forest reached the level of cleanliness.
