地表径流与土壤渗透拟合方程

为了处理在野外测试中得到的地表径流和土壤渗透资料,采用了曲线拟合方法。通过处理,建立了降雨时间与地表径流系数、渗透时间与土壤渗透量、渗透时间与渗透速度关系方程,在比较两组方程中,选取了具有较佳拟合效果的一组方程作为在实际应用中的数学模型。

THE DISCUSSION ON CURVE-FITTING TECHNIQUES FOR DATA OF DIRECT RUNOFF AND WATER INFILTRATION

In order to process data of direct runoff and water infiltration through soil from field tesrs, curve-fitting techniques were used. By progressin gestablished equations express mutual relations between rainning time and funoff coefficient, between the time and infiltration capacity, between the time and infiltration velocity, respectively. Selected one from two groups of equations achieve optimum fitting effect and was used as mathematical model in practice.
