Abstract
:利用微型径流小区和人工降雨试验,探讨运用VFSMOD 模型评估和预测引入不同草种生草带后黄土坡面产流产 沙动态特征的可行性。通过土壤物理性质参数和生草带生长状态参数的差异,模型还原了黄土坡面引入白三叶生草带与 百脉根生草带后产流产沙特征的差异及其随生长时期的变化,模拟效果可靠,纳什系数:0.93(径流系数),0.98(修正 后产沙量);归一化均方根误差:6.2%(径流系数),10.9%(修正后产沙量)。当生草带在降雨集中期(如本研究中百脉 根草带9 月上旬)不能保证较好的生长状态和地表覆盖时,其坡面产沙量急剧增大,且明显大于VFSMOD 模型模拟值。 在实际生草带设计时,应避免该情况发生。综上,VFSMOD 模型适用于引入生草带后黄土坡面产流、产沙量的模拟和预测</p
