摘  要:
以关中东部作为研究对象,应用数理统计方法对不同土地利用方式下土壤元素的剖面分布特征的差异性进行分析,探讨了土地利用方式对土壤元素剖面分布状况的影响。研究结果表明:农田中常量元素Al、Fe、K、Na、Ba、Mn、Ti、Mg、Ca在0~20 cm与20~40 cm的含量差异最小,林地次之,花椒地差异最大。重金属元素Sr、Ni、Zn、Co、Pb在0~20 cm与20~40 cm的含量差异亦为农田<林地<花椒地。这对合理利用土地资源具有积极的意义。

摘  要:
The mathematical statistics way was used to analyze the difference of the section distribution feature of soil elements under different soil utilization ways and discuss the effect of different soil utilization ways on the section distribution situation of soil elements.The results showed that the difference of Al,Fe,K,Na,Ba,Mn,Ti,Mg and Ca content between 0~20 cm and 20~40 cm soil layers is the land for planting Chinese prickly ash > forest land > farmland,and the difference of Sr,Ni,Zn,Co and Pb content between 0~20 cm and 20~40 cm soil layers is farmland < forest land < land for planting Chinese prickly ash.
