Dissolved organic matter (DOM) is a small but very reactive pool of organic matter (OM) in the environment. Its role is related to its composition, which depends on its source. In soils, vegetation is the main source of DOM, and biodegradation is the main regulating mechanism. This study aims to characterise DOM produced by contrasted arctic vegetation species and their biodegradation products.

从不同北极植物物种中提取的溶解有机物的特定分子特征在生物降解后仍然存在

溶解有机物 (DOM) 是环境中少量但非常活跃的有机物 (OM) 库。它的作用与其成分有关，而成分又取决于它的来源。在土壤中，植被是DOM的主要来源，生物降解是主要的调节机制。本研究旨在表征对比北极植被物种产生的 DOM 及其生物降解产物。
