Abstract:The rainfall interception in canopy of main forest types, litter storage in forest lands, dynamic changes in water contents, as well as its effect on rainfall interception in Liupanshan forests have been determined in this paper. The infiltration capacity of soil for water and its related factors have also been analysed. It was shown that the interception of rainfall in canopy of main forest types is about 16.2—29.1%, litter storage is 10—12 t/ha, its minimum water-holding capacity is equivalent to the rainfall in 3—6mm, the interception of mainfall in litter is 5.6—13.1%. There is a little water storage in non-capillary pore of forest soil, 233.5—1088.6t/ha in the arbor forest, 390—669t/ha in the bush forest, and 236—475t/ha in the grassland, thus water infiltration rate of soil surface layer is arbor forest, bush forest and grassland from higher to lower.
