中文摘要：

土壤活性有机碳作为土壤有机碳中活跃的化学组分,是土壤有机碳动态的敏感性指标,在全球碳循环中起着非常重要的作用,在当前的研究中,引起了土壤学、生态学和环境学界的高度关注。介绍具有代表性的活性碳组分的表征：溶解性有机碳、微生物量碳、可矿化碳、轻组有机碳、颗粒有机碳等,并对目前国内外常用的测量方法进行简要的阐述。

英文摘要：

Soil active organic carbon as the active chemical component in organic carbon is a sensitivity index of organic carbon dynamics,which plays a very important role in the global carbon cycle and has received wide attention in the fields of Soil science,Ecology,and Environmental Science in the current research.This paper introduces the representative active carbon fractions：the characterization of dissolved organic carbon,microbial biomass carbon,mineralizable carbon,light fraction organic carbon,particulate organic carbon and briefly describes the current commonly used methods in the domestic and foreign research.
