摘　　要：通过室内土柱淋溶试验,对阿特拉津在2种供试土壤中淋溶规律及其影响因子进行了研究。结果表明,淋溶速度由1.8ml/min增至4.4ml/min,阿特拉津的土壤残留量降低,淋出量分别增加10.8%(黑土),8.2%(草甸黑土);同时,增加土壤有机质含量,适当降低淋溶液中H+离子浓度,均有利于抑制土壤中阿特拉津的迁移与流失。研究结论对农业生产的污染防治具有积极意义。Through the soil column eluviation experiment in laboratory,the eluviation law of Atrazine in two kinds of soil and its impact factors were studied.The results showed that：When the eluviation rate was increasing from 1.8 ml/min to 4.4 ml/min,the residues of Atrazine in soil decreased,and the leaching increased respectively 10.8%（black soil）,8.2%（meadow black soil）;At the same time,it was beneficial for inhibiting the moving and outflow of Atrazine in the soil through increasing the content of soil organic matter or ruducing the content of H＋ in the leaching solution.The research conclusion had a positive significance for the pollution prevention of agricultural production.
