摘要
通过对洛川地区黄土构造节理和沟壑水系的研究,发现黄土构造节理及其密集带作为黄土地层的软弱带,使得外营力侵蚀作用尤其是水力侵蚀作用显示了选择性,它们成为沟壑水系和水土流失的构造基础。
Based on the study of loess stuctural joint and gully water system in Luochuan region, it is observed that loess structural joint and its dense belts are the weak belt of loess layer, and soil erosion with exogenic agency, particularly water erosion, has the selectivity, they become the structural basis for soil and water loss and gully water system.
