Abstract:: Aimed to test the effect of different restored vegetation types on soil infiltration capacity and runoff generation. Infiltration processes were measured with double-ring infiltration method in the six restored vegetation types on the eastern side of Funiu Mountains. The likelihood of runoff was inferred by comparing stable infiltration (K_s) at the top soil with prevailing storm intensities in the six restored vegetation types. The results indicated that: (1) the values of soil infiltration variables, including the initial infiltration, stable infiltration, and total amounts of infiltration before 60 minutes were in the sequences of Quercus variabilis secondary forest > Quercus variabilis plantation > Black Locust plantation > Platycladus orientalis plantation > Shrub > abandoned land; (2) soil bulk density, total porosity, non-capillary porosity, soil organic matter, fine root biomass, and water stable aggregate were significantly correlated with the variables of soil infiltration (p<0.05), soil bulk density and total porosity were the main factors affecting soil infiltration; (3) Quercus variabilis secondary forest could resist storm with 10 year recurrence, and Quercus variabilis plantation could overcome storm with 1 year recurrence. On the contrary, runoff was most likely to occur in the shrub land and abandoned land. It is suggested forest conversion and forest plantation with native tree species benefit for increasing soil infiltration capacity.
