摘要

摘要: 通过对重庆市芙蓉洞内两处滴水和两处池水长期定点观测，现场测试pH、温度和HCO-3浓度等指标，并采集适量水样带回实验室利用ICP—OES和离子色谱仪测试主要离子的浓度，计算CO2分压(PCO2)和方解石饱和指数(SIc)，探讨了芙蓉洞内次生碳酸盐的沉积情况及与当地降水的关系。结果显示：四个观测点洞穴水在大部分时间相对于方解石为过饱和水，且正在沉积碳酸盐，可见芙蓉洞地区大部分时间具有洞穴碳酸盐沉积的温度和降水条件；不饱和出现在较大降水量之后的1~2个月内，是降水对岩溶水的稀释作用导致的。因此，降水量的变化是洞穴水呈现过饱和与不饱和交替的出现主要原因，最终导致碳酸盐沉积的季节变化，降水量过大时不利于碳酸盐的沉积。

Abstract: Four monitoring sites were selected in Furong Cave, Wulong county of Chongqing China, including two drip water sites and two pool sites, respectively. The pH, temperature and concentration of HCO-3 in water for the four sites were tested in the cave, other water samples are analyzed in the laboratory for the concentration of some main ions (e.g. Mg2+, Ca2+, K+, Na+, SO2+4, etc.). Then the PCO2(Pressure of CO2) and the SIC (Saturation Index of calcite) were calculated with the WATSPEC software, the sediment of carbonate and the relationship between SIc and precipitation in Furong Cave were discussed. Some conclusions were drawn as follows: in most months of monitoring year, the water of the four sites is oversaturated to calcite, which reflected the stalagmites beneath them are in depositing. Activing sediments on a piece of glass which placed under one drip water in Furong Cave confirmed the results of the calculation of SIC. Furthermore, the SIC of drip water was usually higher than that of pool water in the same season. So the temperature and precipitation was well for the deposition in Furong Cave. And the unsaturated period also after the highrainfall month shows that the precipitation had a big effect on the SIC, so the highrainfall is the key factor for the deposition and lead to the alternate over saturation and unsaturation. 
