Soil water holding and infiltration parameters were measured in the research on soil hydrological processes for four different plantations

which wereCunninghamialanceolata×Pinusmassoniana

Lithocarpusglaber×Schimasuperba×Cinnamomumcamphora×Liquidambarformosana

Lithocarpusglaber×Schimasuperba

andCunninghamialanceolata×Pinusmassoniana×Schimasuperba

in Simian mountain of Chongqing City.Results indicated that the saturated soil water holding capacity in mixed broadleaf conifer forest was the maximum of 314.98 mm;broadleaf forests

301.26 mm and 290.26 mm;and coniferous forest

the minimum of 237.94 mm.The values were 44.93%

38.61%

33.72%

and 9.48%higher than those in barren land

respectively.Soil infiltration rate inLithocarpusglaber×Schimasuperbabroadleaf forest was maximum

with the initial rate of 25.35 mm/ min

the stable rate of 3.97 mm/ min

and the averaged rate of 5.48 mm/ min.The grey relational grade analysis indicates that the two different mixed broadleaf forests are able to adjust and conserve maximal daily rainfall.Broadleaf forest mixed by Lithocarpusglaber×Schimasuperba×Cinnamomumcamphora×Liquidambarformsana has excellent soil water holding capability

while broadleaf forest mixed byLithocarpusglaber×Schimasuperbahas strong soil infiltration efficiency.
