The infiltration rate is intensively affected by rainfall intensity, and there exists a linear relation between the depth of infiltration and precipitation and rainfall intensity.
入渗深度与降雨量和降雨强度之间存在线性关系，土壤渗透能力随土壤剖面初始含水量的增加而减小，土壤稳定入渗速率的时间趋于缩短。
The relations between rainfalls, contents of soil water before rainfall, time of infiltration and depth of infiltration were described.
