摘　　要：通过盆栽试验，研究了土壤－植物系统中酞酸类增塑剂ＤＢＰ、ＤＥＨＰ的迁移和分布．结果表明，土壤中ＤＢＰ、ＤＥＨＰ的降解符合一级反应动力学方程，玉米根、茎、叶中ＤＢＰ的浓度随时间变化趋势是不同的．土壤－植物系统中ＤＢＰ的迁移转化可以用二分室系统模型描述．The degradation, translocation and distribution of DBP (dibuty1 phthalate) and DEHP [2ethy(hexy1) phthalate] were studied by greenhouse experiments in soilplant system. The results showed: The degradation rates of DBP and DEHP were fitted in firstorder kinetics equation. The DBP concentration increase in the roots, stems and leaves of maize plant as a time function were different. DBP transformation and translocation in soilplant system were described by TwoCompartment System model.
