| 摘要: |
| 土壤碳库在全球碳循环中占有重要的地位，土壤有机碳的稳定程度直接影响到其对大气CO2产生碳汇的潜力，土壤钙不仅是盐基离子，能影响土壤pH值，而且对土壤有机碳的稳定性和吸收大气CO2的能力产生影响。本文综述了土壤有机碳稳定机制研究方法，钙对土壤有机质稳定性影响研究进展，以及岩溶区富钙偏碱的地球化学背景下土壤大量钙存在对有机碳稳定性影响的研究进展。 |

| Abstract: |
| Soil carbon pools play an important role in the global carbon cycle.The stability of soil organic carbon directly affects its potential to generate carbon sinks from atmospheric CO2.Soil calcium is not only a salt based ion,affecting soil pH value,but also affects the stability of soil organic carbon and the ability to absorb atmospheric CO2.This article reviewed the research methods of mechanism of soil organic carbon stability,calcium effect on the stability of soil organic matter,and the research progress of the influence of soil calcium on the stability of organic carbon under the geochemical background of a large number of calcium in karst area. |
