摘要
溶解有机质是土壤有机质的重要组成部分,由于其活性较高,可能在土壤C循环过程中发挥相较其含量所占比例更高的作用。本文根据文献资料,分析了目前关于土壤溶解有机质来源、组成、含量动态及转化特征的研究现状,提出了未来研究的重点。
Dissolved organic matter is an important component of soil organic matter (SOM) and plays a more significant role in the cycling of soil organic carbon than the proportion it accounts for in total SOM because of its high biodegradability. Based on the literature, this paper reviewed recent advances in sources, composition, dynamic concentration and transformation of dissolved organic matter in soils, and proposed emphases for the study in future.
