Study on spatial distribution of negative aero-anion concentration in waterfall environment

Study on Spatial distribution of negative aero-anion concentration in the waterfall environment of ShiBiLiuzong. Results showed that the negative aero-anion concentration was decreased with the increase of the distance from the water fall center and the decreased degree tended to mitigation with the increase of the distance from the waterfall center. There was very significant difference among the negative aero-anion concentration in different areas from the waterfall center. The azimuth of observation had some influence on the negative aero-anion concentration. Within the test range, the negative aero-anion concentration reached the highest in the south, took second in the southeast and reached the lowest in the southwest.
