九华山风景区空气负离子水平分析与评价

Analysis and Evaluation on Aero-Anion Concentration in JiuHua Mountain

以九华山风景区不同景观带(街区、林区、香火区和溪边)为研究对象,采用美国空气负离子测量仪对其负离子浓度进行测量,结果表明:1)九华山空气负离子含量和空气清洁度随海拔的升高而增加,到达山体中部达到最大值,然后又逐渐降低,表现出明显的垂直变化现象;2)九华山空气负离子浓度除受海拔高度的影响,还受到天气状况和水体状态的影响;3)不同景观带的空气负离子含量和空气清洁度差别显著,其大小顺序为溪边>林区>街区>香火区。

American air anion detector was employed to measure the aero-anion concentration in different scenic spots（blocks,forest,incense area and stream） in Jiuhua Mountain Scenic Area.The results showed that： 1） Aero-anion concentration and air cleanliness first increased with the exaltation the elevation to the maximum in the middle of the mountain,and then came to decrease,which exhibited obviously the vertical change;2） in addition to being impacted by altitude height,the aero-anion concentration in Jiuhua Mountain were affected by the weather and water conditions;and 3） aero-anion content and air cleanliness in different scenic spots were significantly different,ordered by stream sides forest blocks incense areas.
