摘要
以洛川苹果园与农田土壤为研究对象,分析不同土地利用方式下土壤表层和土壤剖面微量元素含量变化特征。结果表明:不同的土地利用方式对土壤微量元素含量变化的影响差异显著。苹果园表层土壤中Mn、Zn、Cu、As四种微量元素的含量均高于农田,微量元素的分异类型在苹果园和农田土壤中体现出明显的差异性;在苹果园与农田土壤剖面中,各微量元素的分布规律因元素种类而异。
The paper takes the apple orchard and farmland soil in Luochuan as the studied object and analyzes the distribution characteristic of microelements in surface soil and profile soil for different land.The results show that microelements in soils are obviously different for different land use.The contents of Mn,Zn,Cu,As in the surface soil of the apple orchard were higher than surface soil of farmland.The type of differentiation of microelement shows differences between the apple orchard and the farmland soil.In profile soils of the apple orchard and farmland,the distribution of microelement vary by element type.
