Abstract:

Based on the Water Holding Capacity of two typical Litter Layers of Mount Sejila,the results show that:The litter reserves of different levels、the maximum water holding capacity and effectively hold water rate of Pinus densata are more than Arrow bamboo;the maximum water holding rate of different levels forest litter between two typical forest stand are significant，the Maximum Water Holding Capacity of undecomposed Litter layer of Pinus densata is 106.54%，and the Maximum Water Holding Capacity of semi-decomposed Litter layer is 156.93%；the Maximum Water Holding Capacity of semi-decomposed Litter layer of Arrow bamboo is 89.08%，and the Capacity of undecomposed Litter layer is 232.22%，it is 2.6 times of the semi-decomposed layer。During the testing cycle，the sorptive rate and soaking time of Litter are obvious function P = a (t), P = a ? eb (t)，the Water holding capacity and soaking time of Litter are obvious function：Q=aln(t) ＋b.
