土壤有机碳研究进展及在农田生产中的应用

Progress in Soil Organic Carbon Research and It's Application in Farm Production

土壤有机碳在全球变化研究中具有重要地位,其固存与排放对全球气候变化有重要影响。文章回顾了国内外土壤有机碳研究进展及趋势,阐述了全球土壤有机碳库存量及分布、全球碳循环过程、影响土壤有机碳库存量的因素、农田土壤有机碳组成及其影响因素、农田土壤有机碳转化规律及影响因素,指出了我国在土壤有机碳研究方面存在的问题及今后的发展方向。

Soil organic carbon（SOC） pools play important roles in global change. At present,it is one of the most important problems in global change research. Sequestration and emission of SOC have significant impacts on global climate change. This article reviews that progress in soil organic carbon research and tendency,at home and abroad. This paper expounds the global soil organic carbon storage and distribution,the global carbon cycle,the influencing factors of soil organic carbon stock,The constituents of farmland soil organic carbon and its influencing factors,the transform rule of farmland soil organic carbon and its influencing factors. In the study of soil organic carbon in China are pointed out the problems and development direction in the future.
