Abstract: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.
