大气核爆产物137Cs能够强烈地被土壤颗粒所吸附

是一种示踪土壤运移的良好示踪剂。通过对紫色丘陵区响水滩小流域不同地貌部位和不同土地利用类型下土壤剖面中137Cs含量的测定与分析

计算了流域各地貌部位、土地利用类型的侵蚀强度。研究得出该流域137Cs含量的背景值是1870 Bq/m2;流域内坡耕地、林地的年均侵蚀强度分别是4468 t/(km2.a)和1759 t/(km2.a);丘顶、丘坡和鞍部的年平均侵蚀强度分别是2125

4676 t/(km2.a)和3625 t/(km2.a)

槽土和水田则是沉积区。分析结果表明地貌部位和土地利用类型对土壤侵蚀影响巨大

坡耕地是该小流域泥沙的主要来源。
