| 摘 要： | 通过对以米脂、洛川为代表的典型黄土丘陵区、黄土源区的野外考察，认为它们之间存在着黄土披盖形式、地貌发育规律等方面的差异．这种差异明显表现于二者沟谷发育特点及发育规律上，导致沟谷延伸速度的显著不同两地区水上流失形成主要受各自不同的地貌发育规律控制，均需经历一个较长的强水土流失期．

| Abstract: | By means of field study in Mizhi and Luochuan, Shanxi Province, the difference of form of the loess draping and the land form evolution law in the model loess hill and loess tableland area is determined. This kind of difference is showed by the ravine evolution feature and law,and caused the difference of the ravine's extending speed between the loess hill and tableland.The forming of water and soil loss is controlled by its respective land form evolution law in these two areas, and has a long period of strong water and soil loss. |
