中文摘要：
全球碳循环已成为全球气候变化的核心问题之一，岩溶作用对大气CO2浓度的调节以及其与土壤CO2的密切关系也受到了国内外普遍关注。岩溶作用消耗土壤CO2对大气碳库起到了重要的减源作用，对土壤CO2进行研究将有利于进一步揭示岩溶碳循环过程。因此从气候条件、土壤理化性质、土地利用类型等方面综述了土壤CO2的影响因素以及其对岩溶碳循环的影响，并提出其它酸参与到岩溶碳循环中将会减弱岩溶碳汇效应。由于各个因素之间往往相互联系，共同影响土壤CO2和岩溶碳循环，在研究岩溶碳汇时，需以地球系统科学和岩溶动力系统理论为指导，综合考虑大气圈、水圈、岩石圈、生物圈中各种因素的影响。
英文摘要：
The global carbon cycle is an important factor for studying climate change. The adjustment of karstification to atmospheric CO2 concentration and its close relationship with soil CO2 are gaining more attention. The consumption of CO2 by the karstification process can weaken the carbon source of the atmosphere, and the study of soil CO2 is useful for clarifying the karst carbon cycle. Therefore, the effect of climate condition, soil property and land use type on soil CO2 and the karst carbon cycle is examined. Furthermore, the effect of other acids such as HNO3and H2SO4 on the karst carbon cycle is also considered in this review. Because the factors all connect with one another, research on the karst carbon sink must consider every factor and should be conducted in accordance with earth system science and karst dynamic system theory.
