本文通过作物盆栽试验、区域调查、农田径流和淋溶试验以及土壤生化活性和微生物试验,研究了铅在土壤、植物、水体中的迁移和累积,并通过迁移模式的计算得出了铅的土壤临界浓度和环境容量。

Sierozem is zonal soil in China.The migration and accumulation of Lead in atmosphere, soil, plant, water systems were investigated by experiments of potted crops, regional survey, surface runoff and leachate experiment of farmland and test of soil, in the respect of biochemical activity and microorganism,The critical concentration and environmental capacity of Lead in Sierozem were obtained through calculation of migration model.
