可溶性有机质(DOM)是陆地生态系统重要的活性碳源和养分库,在土壤有机质的降解和矿化过程中发挥着关键作用,决定着土壤微生物区系和土壤生物学活性,在森林生态系统生命元素的生物地球化学物质循环中具有重要作用。本文介绍可溶性有机质的基本概念及其研究方法,分析和探讨可溶性有机质的影响因素及其发展趋势。
Dissolved organic matter (DOM) is an important activated carbon source and nutrient pool in terrestrial ecosystem. It plays a key role in the degradation and mineralization of soil organic matter, which determines the soil microbial flora and soil biological activity. In the life of forest ecosystem Elements of the biogeochemical cycle has an important role. This article introduces the basic concepts and research methods of soluble organic matter, analyzes and discusses the influencing factors of soluble organic matter and its development trend.
