| 摘要: |
| 提出用渗水模数、径流模数和泥沙模数这3个指标来衡量土壤-草本植被根系复合体的抗水蚀能力。通过人工模拟降雨试验，分别建立了渗水模数、径流模数和泥沙模数与地面坡度、降雨强度、复合体渗透系数或抗水蚀强度之间的相关方程式，即土壤-草本植被根系复合体抗水蚀能力的土壤力学模型。 |

| Abstract: |
| The modulus of infiltration (MOI),modulus of runoff(MOR) and modulusof sediment (MOS) are introduced as the index for evaluating the anti-water erosion ability of the soil-root composite(SRC). The relationship of MOI, MOR and MOS with the ground slope, rainfall intensity, seepage coefficient and anti-water erosion strength of SRC are found out through the rainfall simulation experiment, which provides thescientific basis for evaluating the soil-water conservation efficiency. |
