摘　　要：本文通过几年来对浙西洞穴气候考察资料的分析,揭示了该区不同类型洞穴各气象要素的时空分布特征及变化规律,并探讨了其形成原因.这为如何合理开发和科学利用洞穴资源以及洞穴气候的理论研究提供了一个实例.According to the climatic abservation of the caves of Western Zhejiarg in recent years, the temporal and spatial distributions and change patterns of meteorologicalfelements in different types of caves in Western Zhejiang are analysed. The results are as follows: 1 . The air movement of the caves with a single entry is dominated by the effect of 'heat couvection' whereas that of the caves with multiple eatries is affacted by the chimney effect. Directions and speeds of the air movement change obviously in different seasons. 2 . Both the daily and annual temperature variation inside the caves are less than those outside the caves, but their mean annual temperature is correlated to a certain degree. In addition, there is a temperature inversion inside the caves, with intensity of 0.2-1.0℃/10m. 3 . Humidity inside the caves, which has no distinctive daily and annual variations, is high all the year around. Relative humidity reaches as high as 90% or higher. 4 . Human effect on the cave micro climate can be measured. Anthropogenic temperature vising of higher than 0.5℃ was an observation.
