| 摘 要： | 为进一步了解洞穴微环境与气候环境指标之间的相互联系,本文以广东英德宝晶宫溶洞为研究对象,对洞穴空气温度、相对湿度、CO_2浓度进行了为期42个月(2011年12月~2015年5月)实地监测,结果发现宝晶宫洞穴微环境存在明显的时空变化:近洞口处洞穴微环境季节性变化特征明显,而洞穴深处微环境季节变化显著变弱。洞穴微环境的变化主要受到外界气候和天气的变化以及通风效应的影响,前者是导致洞穴微环境季节性变化的主要原因,后者是导致洞穴微环境变化具有空间差异性的主要原因。此外洞穴结构和旅游活动也会对洞穴微环境变化产生影响。本研究结果表明,洞穴通风作用是影响洞穴微环境变化的重要过程之一,其对洞穴沉积气候环境指标的影响可能值得今后进一步深入研究。

| Abstract: | Environmental monitoring Result for Baojinggong Cave from December, 2011 to May, 2015, show cave environment including cave air temperature, relative humidity (RH), and CO2 concentration, display obvious temporal and spatial variations. The cave environments show obvious seasonal variation near the entrance relative to those in the deep cave. The variation of cave environments is mainly influenced by the climate or weather changes and cave ventilation. The climate or weather changes result in the temporal variation of cave environments, while the cave ventilation leads to the spatial variation of cave environment. And the special structure of Baojinggong Cave and the tourism activities would also contribute to the cave environments variation. |
