为了研究坡面径流特征，采用上方人工放水实验模拟坡面水流，研究不同放水流量强度、不同坡长及不同坡度条件下红壤坡面径流过程特征。结果表明：（1）不同放水流量强度条件下，坡面径流率随径流历时的变化总体上呈先逐渐增大，后趋于稳定的变化过程，且放水流量强度越小，坡面径流率的增长速度反而越大；（2）不同坡长条件下，坡面径流率随径流历时的变化过程总体上先逐渐增大，后趋于稳定，且随坡长的增大，坡面径流率越小；（3）不同坡度条件下，坡面径流率随径流历时大部分先逐渐增大，后趋于稳定，对于两个较陡坡（50°和65°）且放水流量较大的坡面，坡面径流率随历时先逐渐减小，后趋于稳定。

In order to study the characteristics of slope runoff of red soil,this paper conducts artificial drainage experiments to simulate the slope runoff under different water flow intensity,slope length and gra-dient. The results show that:(1)under the condition of different water flow intensity,the runoff rate in-creases in the beginning but becomes stable later. The growth rate is greater when the flow becomes smal-ler;(2)under the condition of different slope length,the rate changing shows the same tendency,but the figure is smaller when the slope length becomes longer;(3)the same changing pattern is also found in most time under the condition of different slope,but exception is observed in two more steep slopes(50° and 65°)where the pattern is decreasing first before stabilization.
