| Abstract: | The litter storage and hydrological function of broad-leaved forest attacked by a rare ice-snow storm in 2008 in Jiufeng Mountains of Guangdong province were investigated by measuring litter biomass and its water holding capacity using the soaking and weighing method. It was found that the total litter biomass was 25.34 t·hm-2, and the biomass of leaf, branch and trunk were 8.84, 6.01 and 10.49 t·hm-2, respectively. The litter biomass and the proportion of leaf, branch, and stem had close relationship with the extent of damage and damage proportion of sample plots. The water holding capacity of litter layer of leaf, branch and trunk were 27.8, 8.2 and 13.8 t·hm-2, respectively. The weight-based ratio of water holding capacity of leaf, branch and trunk were 314.2%, 136.4% and 131.7%, respectively. The litter soaking experiments showed that the water holding amount increased with soaking time, following a logarithmic curve, while the absorption rate decreased with time, following a power function curve. |
