In order to know the dynamic characteristics of cavern hydrochemistry in bare karst aeration zone, three drip water points in the Xiaoyan cave are selected as the research site, and the dripping rate, conductiv- ity, pH, Ca2＋ , Mg2 , Sr＋ etc. are monitored. The results show that （1） ion concentration of the dripping water is of obvious relationship with temperature and precipitation, and high temperature and rainy weather will speed up karstification, make Ca2＋ , Mg2 content increase, heavy rain will bring about a great fluctua- tion in the concentration; （2） chemical properties are affected by soil and rock roof thickness as well as drip water yield, the thicker the soil layer, the higher the calcium ions content in the water＋ （3） the dripping wa- ter yield of the ＂slow recharge＂ dripping point shows a positive correlation with the ions content, but the dripping water yiel＇d of the ＂rapid recharge＂ dripping point shows a negative correlation with the ions con- tent, and when both ＂slow recharge＂ and ＂rapid recharge＂ dripping water exist at one point, the dripping water yield and ion content change violentlv,and the correlation is positive.
