【摘要】 土壤活性有机碳(Soil active organic carbon)是陆地生态系统的重要组成成分,在陆地碳循环研究中具有非常重要作用。土壤活性有机碳的组分为:微生物有机碳、溶解性有机碳、矿化有机碳、易氧化有机碳和轻组有机碳等。主要综述了代表很大比例土壤有机碳库的土壤活性有机碳的表征、分组及影响土壤活性有机碳周转的主要因素,如水分、湿度、温度、季节和土地利用方式等。更多还原

【Abstract】 Soil active organic carbon,as a main component of terrestrial ecosystem,plays a very important role in terrestrial soil carbon cycle.The active organic carbon in soil involved microbial biomass carbon,dissolved organic carbon,mineralizable carbon,oxidizable carbon,and light fraction.This paper summarized characteristics and significance of Soil active organic carbon,which represented a high proportion of soil organic carbon pool,primary factors of the influencing Soil active organic carbon turnover,Based on this,season,humidity,land use,etc.更多还原
