摘　　要：As the most motive organic fraction in composting,dissolved organic matter(DOM)can contribute to the transfer and dispersal of pollutants and facilitate the global carbon cycle in aquatic ecosystems.However,it is still unclear how composting approaches and conditions influence the properties of compost-derived DOM.Further details on the shift of DOM character indexes are required.In this study,the change in properties of compost-derived DOM at different composting approaches and the effect of composting conditions on the DOM characteristics are summarized.Thereafter,the change in DOM character indexes’in composting was comprehensively reviewed.Along with composting,the elements and spectral properties(chromophoric DOM(CDOM)and fluorescent DOM(FDOM))were altered,size and hydrophobicity increased,and aromatic-C and electron transfer capacity were promoted.Finally,some prospects to improve this study were put forward.This paper should facilitate the people who have an interest in tracing the fate of DOM in composting.
