Studies on the Shrub,Herbage and Litter Hydrological Effect Under Different Forest Type in Badong Area

Through the shrub,herbage and litter amount survey and the water holding characteristic experiment of the litter un- der different kinds of forest.The result shows that the shrub and herbage amount of different forest type is bush forest,Pinus massoniana Lamb.forest,mixed forest of conifer,mixed forest of conifer and broadleaf,broadleaf forest and Cup ressusf unebris Endl.forest in order.The water holding amount of shrub and herbage have positive relative with their amounts.The littera- mount of different forest type is Cupressus funebris Endl.forest,mixed forest of conifer and broadleaf,broadleaf forest,mixed forest of conifer,bush forest and Pinus massoniana Lamb.forest in order.And the water holding amount of litter is broadleaf forest,Cupressus funebris Endl.forest,mixed forest of conifer and broadleaf,mixed forest of conifer,bush forest and Pinus mas- soniana Lamb.forest in order.And the water holding capacity of the litter form is affected with its amount and component.
