摘要
本文通过对瑶琳洞洞穴气候考察资料的分析,初步揭示了该洞开洞前后洞内气温、湿度和气流(风)等气象要素的时空分布特征及变化规律,并对其成因进行了探讨。同时指出,由于洞穴的开发,其内部条件的改变和人为作用对洞穴气候的变化也会产生一定的影响。
By climatic survey and analysis of the Yaolin Cave, the temporal and spatial distribution patterns of the cave meteorological elements such as air temperature, humidity and air currents are revealed in this paper. The basic climatic features of the Yaolin Cave are moderate temperature variation, high humidity, weak ven- tilation and strong temperature inversion. According to the survey, in the case of only one natural entrance, convection caused by air gravitational effect was very weak and air temperature in the cave was quite stable with fluctuation between 17.5-17.7℃. The relative humidity was greater than 95% and the intensity of temperature inversion was about 0.2-0.5℃/ 10m. When the cave was excavated into, the chimney effect intensified air movement in the cave. The rate of air in flow or out flow of the cave in winter and summer seasons is about 3-5m3/s. Subsequently, the yearly and daily cyclic variations and noncyclic variation of temperature and humidity tend to be obvious.
The paper also goes further into the formation of the cave climate. It is pointed out in this paper that owing to the development of the cave for tourism, change of internal conditions and human action may exert certain effects on the cave climate.
