摘　　要：对桂林市西郊的芦笛岩和大岩洞穴环境长期观测的结果表明 ,作为游览洞穴的芦笛岩与洞外空气交换频繁 ,洞穴 CO2 的含量较低 ,温、湿度变化频繁而且幅度大。游览活动导致洞内 CO2 含量显著增加 ,但是回落十分迅速 ,不会引起洞内温度、CO2 的累积效应。作为非游览洞穴的大岩与外界交换弱且缓慢 ,保持着相对恒定的原始环境 ,有较好的洞穴气候分带 ,空气温度、湿度比较稳定 ,CO2 的含量呈规律性季节变化 ;最近 2 0多年来 ,洞内气温。Depending on long-term cave environmental monitoring to the Reed Flute Cave and the Great Cave in the western suburb of Guilin, it indicates that, as a show cave, the carbon dioxide content in Reed Flute Cave is less, rises by tourist activities apparently and gets down quickly, it does not bring about accumulating effect of temperature and carbon dioxide, but temperature and humidity changes obviously with a high frequency because of frequent air exchange with outside. As a non-opened cave, the air in the Great Cave exchanges slightly and slowly with the outside environment and keeps a relative stable original environment with a perfect cave weather zonation, more invariable air temperature and humidity and regular seasonal change of carbon dioxide content. Air temperature and humidity inside the cave descend obviously in the recent 20 years.
