摘要

采用分层取样的方法

对陕北王茂沟小流域土壤有效铜的分布特征进行了研究.在研究区流域内

土壤有效铜的均值高于黄土区土壤有效铜的临界值;沟坡部分有效铜含量最高

峁坡部分有效铜含量最低;不同坡向有效铜含量大小为:半阳坡>阳坡>半阴坡>阴坡;土壤有效铜与有机质在20-30cm土层处相关性最强.

Abstract

The distribution characteristics of available copper in Wangmao gully watershed of Northern Shaanxi Province were investigated using a stratified sampling method.In the studied watershed

the mean value of available copper was higher than the critical value in the loess area.Effective soil copper was found high in slope areas of gullies and low in slope areas of mounds.In terms of slope aspects

the sequence of effective soil copper was semi-sunny slope>sunny slope>semi-shaded slope>shaded slope.The strongest correlation between effective soil copper and soil organic matter was identified in the soil layer of 20-30cm.The research provides solid evidences for studies regarding the distribution of soil trace elements in Loess Plateau region.
