摘　　要：土壤胶体作为性质最活跃的土壤组分之一,对污染物的迁移转化具有重要的调控作用。农业活动会频繁地改变土壤环境的水动力/水化学条件,势必会影响土壤胶体的环境行为。本文首先综述了农业活动对于土壤胶体释放量,以及胶体组分影响的调控机理,其次重点总结了土壤胶体释放量及施肥所引起的土壤胶体组分性质的差异。最后在现有的农业活动对土壤胶体释放特征差异相关研究的基础上,对尚需深入研究的关键问题进行了展望。As one of the most active soil components,soil colloids play an important role in regulating the migration and transformation of pollutants.Agricultural activities will frequently change the hydrodynamic/hydrochemical conditions of the soil environment,which will inevitably affect the environmental behavior of soil colloids.This article firstly reviews the regulatory mechanisms of agricultural activities on soil colloid release and colloid components,secondly focusing on summarizing the differences in soil colloid release and soil colloid component properties caused by fertilization.Finally,based on the existing research on the differences in soil colloid release characteristics caused by agricultural activities,the key issues that require in-depth research are prospected.
