摘　　要：稳定入渗率(稳渗率)是衡量土壤渗透性能的重要指标。采用双环入渗法(RI)、人工降雨法(RS)和Guelph渗透仪法(GP)测估了太行山低山丘陵区油松林地的稳渗率。三种方法测估的稳渗率分别为0.5mm/min,0.35mm/min和0.04mm/min。在此基础上,对比了三种方法的优缺点,可为今后研究提供依据。本研究为太行山低山丘陵区土壤渗透性能的初步研究,存在着测定的样本点不足等问题,需要进一步的研究。Steady infiltration rate is an important parameter reflecting the soil permeability.The paper used double Ring Infiltrometer （RI）,Rainfall Simulator （RS） and Guelph Permeameter （GP） to measure and estimate the steady infiltration rate of Chinese pine land in hilly region of Taihang Mountain.The steady infiltration rate obtained by the three methods was 0.5mm/min,0.35mm/min and 0.04mm/min,respectively.The advantages and disadvantages of the three methods were discussed to offer basis for further researches in future.However,this preliminary study on the comparison of the steady infiltration rate under three methods should be further enhanced because of the lack of sample points in this research.
