Abstract: The study of hydrological benefit of litter fall of different modes of vegetation restoration was conducted in severe degraded areas of upper reaches of Jialing River.The results showed:The total litter stock of the five modes represented a descending order as follows:scrub on burned field(12.85 t·hm^-2) > Robinia pseudoacacia(9.76 t·hm^-2)> R.pseudoacacia-Pinus elliotii mixed forest(9.52 t·hm^-2)> Cyclobalanopsis glauca(6.01 t·hm^-2)> P.elliotii(3.76 t·hm^-2);The capacity of preserving water indicated a descending order as follows:scrub on burned field(33.60 t·hm^-2)> R.pseudoacacia(19.90 t·h-2)> R.pseudoacacia-P.elliotii mixed forest(11.50 t·hm^-2)>C.glauca(8.70 t·hm^-2)>P.elliotii(3.70 t·hm^-2);As for different forest types,the variation in the process of preserving water of litter fall was not remarkable,the amount of sopped water was large before 1 h and comparable stable in the latter 2～4 h,had no significant relationship with the forest biological diversity.Litter's modified interception was at an average rate of 1 253.4 t·km^-2,ranged from 283～2 759 t·km^-2 to 2 759 t·km^-2,different forests represented descending order as follows:scrub on burned field> R.pseudoacacia> R.pseudoacacia-P.elliotii mixed forest> C.glauca>P.elliotii.
