Shuitu Baochi Xuebao, 1999 在地理信息系统的支持下,采用通用土壤流失方程(USLE)及其修改式估算了海南岛现实土壤侵蚀量和潜在土壤侵蚀量,分析了土壤侵蚀因子R,K,LS在海南岛的表现,得到了海南岛现实土壤侵蚀量和潜在土壤侵蚀量的空间分布特征.研究结果表明:中部山区的现实土壤侵蚀量和潜在土壤侵蚀量均较其它地区大.

Shuitu Baochi Xuebao, 2016 植被建设是治理土壤侵蚀的重要途径，特别是坡面土壤侵蚀。退耕还林还草是黄土高原乃至全国最大规模的植被建设工程，黄土高原是该工程的重点地区之一。小流域是土壤侵蚀综合治理的基本单元。通过退耕还林工程实施前后小流域土壤侵蚀的模拟和分析，可以为植被建设成效评估和调整治理策略提供参考。运用修正土壤流失方程RUSLE，在ARCGIS10.2平台下模拟了羊圈沟小流域1984年，1996年，2006年，2012年和2014年5个年份的土壤侵蚀，评估了退耕还林前后黄土高原小流域植被恢复对土壤侵蚀的影响 ...

Shuitu Baochi Xuebao, 2007 以3种侵蚀红壤（轻度、中度、严重）为供试材料,利用干湿筛法获得其不同粒径的水稳性团聚体（〉4 mm,2～4 mm,1～2 mm,0.5～1 mm,0.25～0.5 mm）,分析团聚体中有机质的分布。结果显示,随着侵蚀程度的增强,〉0.25mm水稳性团聚体的含量逐渐下降,而团聚体的分散度却依次升高;无论何种侵蚀程度,湿筛后团聚体的组成均以小粒径团聚体（〈0.25 mm）占优势。轻度和中度侵蚀的红壤,其有机质含量随着团聚体粒径的增大而增大,严重侵蚀的则相反;侵蚀红壤有机质含量和〉0.25 ...
