摘要
对桂林市芦笛岩和大岩进行洞穴空气负离子浓度分布研究结果表明:(1)除疗养地、瀑布等个别区域外,洞内空气负离子浓度普遍较洞外的高,可高出几倍至十几倍;(2)近洞口段洞道空气负离子浓度由外向里可增加1.6至5.6倍,达到某点后趋于平稳;(3)人类活动对洞中空气负离子浓度影响显著;(4)洞穴空气中的负离子浓度与湿度呈正相关;(5)在所测的八个月里,即2003年9月至2004年4月,洞穴空气负离子浓度在12月和1月较低。
The study on the distribution of aero-anion concentration in the reed flute cave and the great cave shows： （1）Except for few regions such as sanatorium or waterfall, the aero-anion concentration in caves is higher than that outside of the caves generally, which can be one hundred times higher. （2） The aero-anion concentration increases from the outside to the inside of the cave, and after reaching a certain value it tends to be stable. （3） Human activities affect the aero-anion concentration inside the cave remarkably. （4） The aero-anion concentration and the relative humidity inside the cave show positive relationship significantly. （5） The aero-anion concentration in caves is lower in December and January during the monitoring period of 8 months from September, 2003 to April, 2004.
