中国西南地区土壤有机碳研究现状与展望

The Status and Prospect of Soil Organic Carbon in Southwest China

土壤有机碳是反映土壤肥力和评价土壤质量的重要指标,同时对环境的可持续发展发挥着重要作用。文章主要从土壤有机碳库及碳储量、西南地区喀斯特地区土壤有机碳研究、有机碳分组方法的应用等几方面对我国西南地区土壤有机碳的研究现状进行了分析总结,为提升西南地区农田土壤肥力、固碳潜力及农田的可持续利用提供指导及理论依据。

Soil organic carbon is an important indicator of reflecting soil fertility and evaluating soil quality , meanwhile, it plays an important role to the sustainable development of the environment. This paper mainly from the soil organic carbon pool and carbon stor- age, soil organic carbon in Karst area in Southwest China, the present situation of the research on soil organic carbon in Southwest Chi- na, several aspects of the application of organic carbon fractianation methods were analyzed and summarized, in order to improve soil fertility in southwest area, to provide guidance and theoretical basis for the sustainable utilization of carbon sequestration potential farm- land.
