In order to analyze the influence of land use on soil and water resources,the character of runoff and sediment in different land use should be studied, particularly the relation with rainfall character.The laws of runoff and sediment in different land use varying with rainfall, intensity and erosivity of rainstorm, are pointed out, and their subsection character are laid stress on. Runoff and sediment, and their reduction in different land use all mainly occur in I₃₀≥0. 4 mm/ min,P≥50 mm, as well as their differences. Meantime, runoff and sediment and their reduction in different land use showed a seasonal characteristic.
