摘　　要：系统地研究了土壤中不同形态铬的转化机制，从理论上和实验结果上探讨了土壤中铬的氧化还原、吸附、解吸、结合作用机制和相互关系及环境因子的影响；探索了土壤中铬的迁移、转化和积累的规律，同时辅以盆栽试验，研究了土壤中不同形态的铬对水稻生长发育的影响和吸收积累的关系，初步明确了土壤中不同形态铬的污染行为和生物效应的差别。oth laboratory and greenhouse experiments were carried out to studytransforma-tions of diferent forms of chromium in soils and their effects on rice growth. The study not onlyelucidates the mechanisms of soil chemistry involving oxidation/reduction,sorptlon/desorption.precipitation and complexation processes of chromium in soils as well as their relations,but alsoevaluates the chemical,behavior and toxicity of chromium to plants.
