Comparative Study on Determining Methods of Soil Moisture Infiltration in Urban Green Space of Kunming

Soil moisture infiltration rate is a key to determine the infiltration of precipitation and slope runoff percentage,but also an important factor of soil moisture circulation and soil erosion models.By using methods of artificial rainfall,double infiltration,infiltration of Guelph,indoor ring knife infiltration assay,permeation experiments and analysis of urban green space in Kunming,have been carried out,the results showed the determination of soil moisture infiltration rates were significantly different.Through the comparison of soil moisture infiltration process line,the double-ring infiltration experiment which was the most closest to the rainfall infiltration process was the most suitable method for the infiltration experiments to determine soil moisture infiltration.
