【Abstract】 Based on theoretical analysis, it is proved that the capability of farmland in reducing soil erosion will be improved when slope land is built into terraced field, because the original micro-topography is changed. The runoff plot experiment shows that terraced field can reduce soil erosion by 92%~100% compraing with slope farmland.更多还原
