Shuitu Baochi Xuebao, 2008 利用137Cs示踪方法,对宁南黄土高原阳洼流域纵断面土壤137Cs分布及相关影响因子进行了初步研究。结果表明:流域纵断面137Cs面积活度随坡面海拔和水平距离的变化,表现为一种不规则的波动振荡趋势。随海拔降低,纵断面上、中部137Cs面积活度逐步下降,有明显的土壤侵蚀发生;坡面下部137Cs面积活度最高,泥沙沉积的再分布现象明显。流域内林草地剖面土壤137Cs呈指数型分布,坡耕地、梯田137Cs在耕层内呈均一分布,其分布模式与各土地类型土壤有机质的分布状态完全一致。相关分析表明 ...

, 1996 通过不同地域尺度(黄土高原和安塞丘陵沟壑区)土壤中137Cs的分布、分异分析讨论，对137Cs含量和土壤粒径组成的相关性分析，特别是土壤137Cs分布受地貌类型及其它侵蚀因素影响显著性的讨论，表明在黄土高原土壤137Cs含量与粘粒呈正相关，与粗砂粒含量呈负相关，在影响土壤137Cs分布的诸因素中，地貌的影响是最重要的，这为137Cs法研究黄土高原土壤侵蚀的可行性提供了科学依据。对现有国内外利用137Cs法估测土壤侵蚀量的数学模型的适用条件和特点进行分析比较 ...

Shuitu Baochi Xuebao, 2003 研究了黄土高原地区土壤颗粒及有机质对137Cs分布的影响以及137Cs与有机质的关系.结果表明,137Cs与土壤颗粒的剖面分布趋势并不一致,而只是与某一粒级在某一深度上表现出一致性.137Cs与有机质的剖面分布则因不同的利用方式而有所差异.对于非耕作土壤,137Cs与有机质主要分布在土壤剖面的表层;而对于耕作土壤,由于人为的耕作作用,137Cs与有机质都均匀分布在耕作层中.土壤中的137Cs含量与有机碳含量的相关分析表明,两者之间呈显著相关,相关系数为0.791.
