摘　　要：对山东淄博开元洞进行了为期15个月的监测,获取了洞穴内部和外部空气的温度、CO2体积分数、相对湿度数据,并与研究区域附近同期气象数据进行对比分析,探讨了洞穴微气候环境各指标的变化特征及影响因素.研究发现,开元洞洞穴微气候环境对外界气候变化响应迅速,各监测点的空气温度及CO2体积分数变化与外界气候变化有同样的季节变化特征,能够快速响应外界的气候环境变化,季节变化上都体现为夏高冬低;而洞内空气相对湿度的季节变化特征则与洞外相反,表现为夏低冬高,与洞外空气大致相反.监测点KY1点的空气温度和相对湿度的波动变化相对较大,这与其距离洞口较近、存在较强的洞穴内外空气交换有关.A 15-month cave monitoring has been carried out in the Kaiyuan Cave, Zibo City, Shandong Province. The cave air temperature, CO2 volume fractior and relative humidity of the internal cave and external cave were acquired and compared with the contemporaneous meteorological data near the study area and discussed the variability of these indices. The results were as follows： As is different to the external, the same seasonal variation characteristics were founded in cave air temperature and CO2 volume fractior of the internal cave environment, and responded to the change of climate and environment outside the cave quickly. The seasonal variations were high in summer and low in winter. The air relative humidity of the internal cave was contrary to the external cave, and the air relative humidity inside the cave was low in summer and high in winter, while the air relative humidity outside the cave was high in summer and low in winter. According to the spatial differences of the three monitoring points in the cave, the fluctuation of the cave air temperature and relative humidity of KY1 which is the closest to the entrance was relatively large, because KY1 was near the mouth of the cave and the air change movement was relatively stronger.
