摘要
溶解性有机质(DOM)对土壤中有机物的迁移转化有重要作用,也受众多因素影响。介绍了DOM的基本概念、分类和环境作用;讨论了DOM的来源、DOM的分子量大小、DOM的浓度和p H值等影响因素对DOM与有机物的作用并分析了原因;提出了研究的走向。
Dissolved organic matter（DOM） plays an important role in the migration and transformation of organic matter in the soil,and it is also affected by many factors.In this paper,the basic concept,classification and environmental effects of DOM were introduced.The factors affecting DOM and organic matters were discussed,such as p H value and source,molecular weight,concentration of DOM.And the reason was analyzed.Finally the research direction in the future was proposed.
