Based on the infiltration experiments using two size disc infiltrometers, the characteristics of the soil hydraulic properties at four different pressure heads (-9, -6, -3, and 0cm) were analyzed under four land uses. The results showed that the infiltration rates were not obviously different tested by infiltrometers with different diameter discs. The infiltrometer with small disc was more suitable for the field determination of soil hydraulic properties. With the decreasing of the pressure head, steady infiltration rates of the 4 soils decreased to different extents. Soil hydraulic conductivity and Gardner α were determined according to the experimental data at different negative water pressure heads, which were obviously different with land uses. Land use had significant effects on the contributions of macropores and micropores to flow. The contribution of each class pore to flow was reduced with the decrease of the pore size under tea garden and grass land. However, the contributions of micropores (<0.1mm) to flow were kept the highest level in vegetable field and protected field. The result could provide references for estimating hydraulic parameters of soils in hilly area of South China.
