Shuitu Baochi Xuebao, 2000 研究结果表明＞0.25mm的水稳性闭粒含量可作为北盘江中游地区土壤抗蚀性指标。土壤抗蚀性与土壤有机质成正相关，与土壤石砾含量成负相关，但按影响土壤抗蚀性大小，影响因子的排序是：土壤石砾含量＞岩性＞土壤有机质＞坡度＞土地利用类型；建立了4个预测土壤抗蚀性的数学模型，这些模型具有较高的精度，其中两个模型可直接用于野餐测定。

Shuitu Baochi Xuebao, 2023 为揭示黄土高原地区土壤可蚀性(K)的空间分布特征和影响因素,基于EPIC模型、几何平均粒径模型、Torri模型估算黄土高原地区K,并结合地理探测器比较土壤理化性质、海拔、坡度等要素对K空间分布的影响。结果表明:(1)EPIC模型、几何平均粒径模型、Torri模型估算的黄土高原地区K均值分别为0.036,0.034,0.041 。黄土高原以中可蚀性和中高可蚀性的土壤为主,不同模型对K的估算值有显著差异(F=4.460,p＜0.01)。(2)黄土高原K有较为显著的空间异质性,东部和西南地区K较高 ...
