摘　　要：系统地综述了DOC的来源、组成、性质、影响因素、环境效应及测定方法等。尽管关于土壤DOC的研究目前还不完善,至今对DOC的组成、性质等问题都不是很清楚,但现有的研究已经表明,DOC是土壤圈中一种非常活跃的化学物质,它对土壤中化学物质的溶解、吸附、解吸、迁移和毒性等行为均有显著的影响。Researches on dissolved organic carbon (DOC) have been increasing in ecological system. The sources, components, ef-fected factors, environmental effects and measure methods arc reviewed in the presented paper. Although much more studies on DOC should be conducted to understand the behavior of soil DOC in the future, it is clearly indicated that DOC is an important active chemical component in soils. Researchers widely believe that the solution, adsorption, desorption, transport and some other processes of pollutants are enhanced predominately due to their complexation with DOC.
