通过对贵州毕节地区两个处于不同石漠化等级条件下的洞穴朝营洞（潜在）与韩家冲洞（强度）滴水的滴率与元素进行了为期1年的监测，分析了各洞穴上覆的土壤、基岩元素，探讨了滴水的元素来源及其石漠化效应．结果表明，朝营洞上覆土壤元素Ca、Mg、Sr含量高于韩家冲洞；朝营洞滴水Ca2＋、Mg2＋、Ba2＋、Sr2＋平均浓度分别为60．81、3．24、0．012、0．085 mg·L－1，韩家冲洞滴水分别为58．39、2．47、0．01、0．074 mg·L－1；地表石漠化程度越严重，洞穴滴水滴率对大气降雨的响应越敏感，季节变幅越大，滴水元素受到上覆基岩的贡献程度越高；受地表石漠化效应的差异影响，朝营洞滴水元素离子浓度呈现出雨季高旱季低的变化规律，而韩家冲洞滴水元素离子浓度呈现出雨季低，旱季高的变化规律．
The elements source and rocky desertification effect of drip water were explored in caves under different rocky desertification, which are Chaoying Cave ( potential) and Hanjiachong Cave ( intense) in Bijie, Guizhou. An in situ monitoring was carried out on their drip elements and drip rates throughout a year to analyze the overlying soil and bedrock elements respectively. Results indicated that the contents of Ca, Mg and Sr in the overlying soil of Chaoying Cave were higher than those of Hanjiachong Cave. The mean concentrations of Ca2+, Mg2+, Ba2+and Sr2+in the drip water were 60. 81, 3. 24, 0. 012 and 0. 085 mg·L-1 in Chaoying Cave and 58. 39, 2. 47, 0. 01 and 0.074 mg·L-1 in Hanjiachong Cave. Drip rates responded more sensitively to rainfall along with more severe surface rocky desertification. The overlying bedrock contributed more to drip water elements when the seasonal variation was large. Ion concentration of drip water in Chaoying Cave rose in the rainy season and fell in the dry season, while in Hanjiachong Cave the pattern was opposite. This was attributed to the discrepancy of surface rocky desertification effect.
