摘要
大量研究表明耕地具有巨大的固碳潜力,如何通过合理的农业措施使耕地变为有效碳汇,成为农业生态学研究的焦点。笔者对近年来各种农业措施,如耕作方式、施肥措施、种植制度等对于土壤碳固定影响的研究进行了全面综述,总结了当前农业土壤固碳研究现状,分析了不同农业措施对于土壤固碳效应的影响及其机理,及目前研究中存在的问题,指出未来研究中需要加强和深化的方向,并提出相关建议。
A large number of studies showed that farmland had great potential for carbon sequestration,how to use reasonable measures to make agricultural land as an effective carbon sink became the focus of agricultural ecology.In this paper,recent researches about effects on soil organic carbon sequestration produced by agricultural practices such as tillage methods,fertilization and planting system were summarized.The current status of research of agricultural soil carbon sequestration were concluded,the influence of different agricultural practices on soil carbon sequestration and its mechanism were analyzed,and problems in current researches were also analyzed.The future direction was indicated and the relevant suggestion was provided.
