岩溶成土过程为Ｃ、Ｃａ、Ｍｇ淋失，Ｆｅ、Ｍｎ、Ｃｕ、Ｐｂ、Ｚｎ和酸不溶物相对累积的地球化学过程。试验场生物碳库量巨大，实验表明：植物残体在第一季度快速分解，可产生大量ＣＯ２参予岩溶作用；岩溶土壤有机碳含量高、储量大，表层土、鞍部、坡地土松结态有机碳含量高，为岩溶ＣＯ２的潜在来源；土壤有机碳可被酸性溶液（ＫＭｎＯ４）氧化，Ａ层土比Ｂ层土更易被氧化。土壤ＣＯ２含量、释放的野外监测实验结果：湿润气候条件下岩溶作用较为发育。Ｃ１３特征表明：土壤有机碳为土壤ＣＯ２的主要来源，土壤ＣＯ２为岩溶泉ＨＣＯ－３不容忽视的重要来源。土壤、有机质对石灰岩溶蚀实验表明：土壤有机质对石灰岩溶蚀具明显的促进作用，雨季比旱季、坡地比洼地岩溶作用更加发育。
The karst soil-forming process is the geochemical process of C, Ca, Mg leaching, and the relative accumulation of Fe, Mn, Cu, Pb, Zn and acid insolubles. The biochar stocks in the test site are huge. Experiments show that plant residues decompose quickly in the first quarter, which can produce a large amount of CO2 to participate in karstification. Karst soil has high organic carbon content, large reserves, surface soil, saddle, Organic carbon content is high, which is the potential source of karst CO2. Soil organic carbon can be oxidized by KMnO4, and layer A soil is more easily oxidized than soil layer B. Soil CO2 content and field monitoring results released: The karstification is more developed under humid climatic conditions. The characteristics of C13 indicate that soil organic carbon is the main source of soil CO2 and soil CO2 is an important source of HCO-3 that can not be ignored. Soil and organic matter dissolution experiments on limestone show that soil organic matter can obviously promote the dissolution of limestone. In the rainy season, the karstification of the slope is more developed than the depression.
