摘要：在样地调查的基础上,对2008年冰雪灾害后广东乐昌杨东山十二度水自然保护区九峰山不同海拔受损阔叶林枯落物量、持水量、持水率、吸水速率进行了研究。结果表明:林地枯枝落叶层总量为25.34 t.hm-2,其中叶、枝、干分别为8.84、6.01、10.49 t.hm-2;枯落物量及各组分的比例与样地植株受损形式、受损比例之间有密切的关系。枯落物持水实验表明:各组分中,叶、枝、干的最大持水量分别为27.8、8.2、13.8 t.hm-2,最大持水率分别为314.2%1、36.4%、131.7%;叶、枝、干的持水量、持水率随浸泡时间的增加呈自然对数曲线增长,各组分的吸水速率随浸泡时间的增加呈幂函数曲线降低。
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.
