不同经营管理条件下土壤有机碳及其组分研究进展

Research advances in soil organic carbon and its fractions under different management patterns.

土壤有机碳能够反映土壤质量和土壤健康,是当前国内外学者开展研究工作的重点之一.土壤有机碳及其组分的研究已取得了一些成果.本文概述了土壤有机碳分组方面的研究结果,主要讨论了在不同利用类型和不同经营方式条件下,土壤有机碳及其不同组分分解、蓄积、含量、存量、分配比例等的动态变化,并指出了当前土壤有机碳及组分研究面临的一些问题和今后的研究方向.

Soil organic carbon can reflect soil quality and soil health, and is one of the hotspots in related researches at home and abroad. This paper reviewed the research results on the fractionation of soil organic carbon, with the focus on the dynamics of soil organic carbon and its fractions in their decomposition, accumulation, content, storage, and allocation proportion under different land use type and management pattern. Some related issues and further research directions were discussed.
