【摘要】 对２个白浆土和３个草甸土亚类及３个暗棕壤亚类土壤剖面，共计２６个样品，进行了微量元素Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ的全量和有效态含量分析。结果表明：全量与有效态铜、锰之间呈正相关：锌在草甸土上成正相关，而在其它两个土类成负相关；铁在供试土壤上均呈负相关。全量和有效态四种元素与ｐＨ值在不同土类间表现各异。从剖面分布看，随着层次加深，四种元素的含量在不同土类间有明显差异。更多还原

【Abstract】 These authors analyse the content of complete quantity and available Cu,Zn, Fe, Mn,in the profile of two lessive,three subgroups of meadow soil and three subgroups of dark brown earth soil.There are 26 samples together. This result show:Correlativity between complete quantity and available Cu、Mnis direct proportion. Zn is direct proportion in meadow soil. but it is inverse proportion in other two soil.Fe is inverse proportion in three kinds of soil.Fourelements of complete quantity and available differ from pH value in differentsoil. This profile distribution shows that with the depth increasing,the content of four elements is obviously different among different soil great group.Its variety assumes irregular normal distribution.更多还原
