土壤有机碳与土壤肥力和气候变化密切相关而成为当今土壤学等相关领域的研究热点之一。由于土壤有机碳是具有某一特性的一类化合物的混合物,存在高度异质性,所以选用合理的方法有效区分不同碳组分是深入研究土壤有机碳的关键。首先回顾了土壤有机碳的传统分组方法 (包括物理分组、化学分组和生物分组),进而介绍了Stewart等人近年提出的土壤有机碳物理-化学联合分组方法,最后对土壤有机碳分组方法的未来趋势进行了展望。
Soil organic carbon is closely related to soil fertility and climate change and has become one of the hot topics in related fields such as soil science. Since soil organic carbon is a heterogeneous mixture of compounds with certain characteristics, choosing reasonable methods to distinguish different carbon components effectively is the key to in-depth study of soil organic carbon. Firstly, the traditional methods of grouping soil organic carbon (including physical grouping, chemical grouping and biological grouping) are reviewed. Then the recent introduction of the physicochemical-chemical combination grouping method of soil organic carbon proposed by Stewart et al. Is introduced. Finally, the future of the soil organic carbon grouping method Trend outlook.
