Through the survey of forest litter from amount and experiment of water holding characteristics in six kinds of forest stands (the forest of Cupressus funebris Endl. , the mixed forest of conifer,the mixed forest of conifer and broadleaf,the forest of broadleaf,the forest of Pinus massoniana Lamb. and the bush forest) in the Lianxia River watershed in the Three Gorge Reservoir Area, some characteristics parameter of forest hydrology were gained, such as the different kinds of forest litter form amount, the maximum water capacity and water absorb speed. The results showed that the amount of the litter form is the mixed forest of conifer and broadleaf, the pure foest of Cupressus funebris Endl., the forest of Pinus massoniana Lamb., the mixed forest of conifer, the forest of broadleaf and the bush forest in quantity order. The maximum water capacity of the undecomposed litter form is the forest of Cupressus funebris Endl., forest of conifer, the bush forest, the mixed forest of conifer and broadleaf, the forest of broadleaf and the forest of Pinus massoniana Lamb. in quantity order. The maximum water capacity of the halfdecomposed litter form is the forest of Pinus massoniana Lamb., the mixed forest of conifer and broadleaf, the forest of Cupressus funebris Endl., the mixed forest of conifer, the forest of broadleaf and the bush forest in quantity order. In this watershed, the water capacity of the litter form of the forest of Cupressus funebris Endl. is the most, and conifer, mixed forest of conifer and broadleaf, forest of Pinus massoniana Lamb., forest of broadleaf and bush forest follow the next in order. When there is litter form covering soil only and there is no water infiltration and no water running off from ground surface, the maximum rainfall amount and the maximum rainfall intensity in different forest stands different.
