由于全球变暖引发的一系列环境问题,已经受到越来越多国家的重视,引起越来越多科学家们的关注。农田土壤,在全球碳循环中作为大气二氧化碳的源和库,其发挥的作用逐渐显现。本文围绕土壤固碳的基本问题,总结土壤有机碳固定机制及影响因素的国内外研究进展。
As a series of environmental problems caused by global warming, more and more countries have been paying attention, arousing more and more scientists’ attention. Farmland soil, the role of carbon dioxide as a source and reservoir of atmospheric carbon in the global carbon cycle, gradually becomes apparent. This paper focuses on the basic problems of soil carbon sequestration and summarizes the research progress of soil organic carbon fixation mechanism and its influencing factors at home and abroad.
