摘要
本文通过研究人类耕垦与坡面形态演化过程的关系,定量分析人类耕垦活动对现代侵蚀的影响作用,初步估算在陕北黄土丘陵沟壑区,由于人为耕垦活动,坡面侵蚀量可增加25%左右。
The effect of human reclamation on modern erosion was puantitively analyzed by study on relationship between human reclamation and evalution process of sloping sur face, It was estimated that in loess hilly and gully region, the slope erosion might be increased about 25% by reclamation and cultivation.
