摘要: 土壤生态环境是一个复杂的多介质多界面体系.尽管关于土壤溶解性有机质的研究还不完善,但现有的研究表明,它是这一环境中最为活跃的化学组成之一.由于土壤溶解性有机质在C、N、P和S等营养元素的生物地球化学过程、成土过程、微生物的生长代谢过程、土壤有机质分解和转化过程以及土壤污染物的迁移过程有着重要的作用,因此已成为土壤科学、生态科学和环境科学交叉领域的研究热点.本文从土壤溶解性有机质的提取方法、来源、组成、含量和影响因素、生物有效性及环境意义等方面的研究进展作了简要的论述,同时提出了未来的研究方向.

Abstract: Soil is a complex ecosystem with multi-interface. Anumerous studies on soil dissolved organic matter (DOM) were carried out, and proved that DOM was one of the most active chemical components in the environment. Increasing attention has been paid on the study of soil DOM, especially in recent years, and the study has become an interdisciplinary focus in the fields of soil science, ecology, and environmental science due to the important roles of DOM in the biogeochemical cycles of carbon, nitrogen, phosphorus, sulfur, etc. In addition, DOM has significant effects on pedogenesis, growth and metabolism of soil microorganisms, decomposition and transformation of soil organic matter, and transport of pollutants in soils. The recent literatures about extraction methods, origin, composition, contents and controlling factors, bioavailability,and environmental significance of DOM were therefore reviewed, and future research aspects on this topic were also proposed.
