Results reached by runoff-erosion simulating experiment indicated that: toe runofferosion rate in farmland, forest land and grass land decreases with time;
采用径流侵蚀模拟试验的结果表明,在农地、林地、草地、荒坡条件下,侵蚀率随时间的增加而逐渐减少;

Water absorption is greatly reduced; consequently runoff is increased, resulting in accelerated erosion rates.
