摘要
土壤有机碳动态是土壤碳循环研究中的关键,虽然取得了一定的成果,但仍存在许多问题急需解决。本文综述国内外影响农田土壤有机碳(SOC)动态的因素,列举近年来SOC动态研究中新方法的应用,综合评价各方法的优缺点和适宜使用范围;提出SOC动态研究中存在的问题,并指出今后SOC可能的研究方向。
Study on soil organic carbon dynamics is the key of study on soil carbon cycling. Although a rapid progess was made lately ,there are many questions needed to be solved . The advancement of factors influencing dynamics of soil organic carbon(SOC) in cropland was summarized in this paper,new technologies in the study of SOC were introduced, their advantage and disadvantage were evaluated and a use level was identified; The questions for studying the dynamics of SOC were put forword, meanwhile,and the future research directions in study were suggested.
