Abstract:: In order to provide a basis for the construction and planning of soil and water conservation forests of Taihang Mountain, the research for the water-holding capacity of litter was carried out in the four typical forests including Castanea mollissima Bl.forest, Malus pumia Mill.forest and controlled forestland. The litter water holding capacities in different kinds of forest stands were measured by indoor soaking method. The results showed that the litter total storage ranged from 6.62 t/hm² to 15.83 t/hm²; the maximum water-holding volumes of different forests varied from 13.41 t/hm² to 53.9 t/hm²,the order was Castanea mollissima Bl.forest > controlled forestland > Malus pumila Mill.forest; the effective retaining amount of litter was maximum in Castanea mollissima Bl. forest, while the minimum was found in the controlled forestland. The relationship between water-holding capacity of litter and immersion time could be described by logarithmic relationship (R>0.97), whereas the relationship between litter absorption rate and immersion time could be described by exponential relationship (R>0.98). Therefore,it was concluded from above that the water holding capacities of forestlands were much better than controlled forestland.
