摘要
以湖南省桃林铅锌矿区为试验区,通过水稻盆栽、田间小区、大田、农田地表径流和淋溶等试验以及土壤酶和微生物试验,研究土壤铅对土壤-作物(水稻)、土壤-微生物和酶、土壤-水体三体系的各种效应,得到各单体系中铅的临界含量并确定了红壤性水稻土中铅的临界含量,通过铅的平衡试验,建立了土壤铅环境容量数学模型,得出红壤性水稻土的铅环境容量。
The systems of soil-crop, soil-microorganism and enzyme, and soil-water in an experimental field near a lead-zinc mine in Tao Lin, Hunan were investigated by pot trial, field-plot experiment, field test, runoff and leachate measurement, and soil enzyme and microorganism examination. Based on the criteria values of lead concentration in each system derived, the background and polluted values of soil lead content, a model was developed to calculate the environmental capacity of the paddy soils for le-ad in the area
