摘　　要：主要研究了第四纪红色粘土上发育的不同质地土壤（轻壤、中壤、重壤）及分别由第四纪红色粘土和片麻岩发育的相同质地土壤（重壤）对铜的吸附──解吸性能，结果表明，由同种母质发育的不同质地土壤对铜的吸附量大小是重壤＞中壤＞轻壤；它们的临界值大小也与之顺序相同。而由不同母质发育的相同质地土壤对铜的吸附量大小是第四纪红色粘土＞片麻岩，其解吸率大小与之相反。The characters of copper adsorption of the soils of different textures which developpedfrom Quaternary Red Clay soil and those of the soils of the same texture from different mothermaterials were studied.The results shwed: when the mother materials were the same,thecopper adsorption of the soils of three kinds of textures was heavy loam>medium loam> lightloam; when the texture was the same,the adrorption of the soils which developped from differ-ent mother materials was Gneiss soil<Quaterinary Red Clay soil,but the copper desorption ofGneiss soil was higher than that of Quaterinary Red Clay soil.
