| 摘 要： | 本文通过人工模拟降雨技术,在46个测点上取得实测资料。采用曲线拟合法,得到了时间与地表径流系数的关系方程、渗透时间与渗透总量的关系方程、渗透时间与渗透速率的关系方程、渗透速率与渗透总量的关系方程,这些方程分别采用y=a(1-e~)~b、y=a+bx+cx~2、y=f_c+(f_o-f_c)e~、y=ae~(b/x)模型时,可以得到良好的拟合效果。并对46个测试区都作出了实测曲线的拟合方程,还对其渗透特性作了探讨。

| Abstract: | In this paper.applying artificial simulated rainfall technique,information of 46 measuring points have been got. The following regress, ion equations have been got through curve-fitting method of the above informations. That is.surface runoff vs. time;infiltration capacity vs. infiltration rate. The best fitting results are got if these equations use the following model forms: y=a(1-e~)~b,y=a+bx+ca~2.y=J_+(f_0,-f_)e~,y=ae~. Curve fitting equations of all measuring points have been created. The authors have discussed the runoff and infltration characteristics. |
