摘要
因为黄土区中小流域地形地貌复杂,影响径流的水文气象资料较难获取,故在无资料地区的小流域设置因子径流场对降雨产流进行预报和计算;利用美国水土保持局提出的降雨SCS计算模型对因子径流场径流量进行了分析计算.结果表明,计算值与实测值拟合效果较好,能够满足同类地区对因子径流场产流量的预报.另外,因子径流场具有资料易于获得,且简便易观测等特点.
The hydrometeorogical data which affect run-off attain uneasily because of complex terrain and landscape in loess region. Setting up factorial run-off plot forcasts and calculates runoff yield in small watershed without data;it can be attained easily and observed simply. Using SCS model proposed by Water and Soil Administration of USA calculated runoff yield of factorial runoff plot. The result showed that test of fit was better between the calculable consequence and the observed consequence, and the SCS model could satisfy the forecast to runoff yield of factorial run-off plot in same region. And factorial runoff plot has features such as attaining data easily and being observed simply.
