| 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。

| Abstract: | 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. |
