- Abstract:
-
Dark coniferous forest grows in the Plateau mountain region of Mountain Sejila in Tibet.This stand grows well. Undergrowth of vegetation is rich. The rather thick bryophyte grows on the surface of understory. Water holding capacity and species identification in different aspect altitude of mount Sejila in Tibet were studied by field survey and water immersion. The results showed that: there were 9 families, 13 genera and 14 species among these specimens, the predominant species was Thuidiaceae Actinothuidium hookeri, which distributes at every elevation. The thickness of moss on shady slope is higher than sunny slope of Mountain Sejila in Tibet. Whether the water holding capacity or the maximum water holding capacity on shady slope is higher than that on the sunny slope. The water holding capacity on two aspects with 3 800 m altitude is the biggest. The water holding capacity of moss increased rapidly after moss was soaked for 0.5~1 h. The water holding capacity increased slowly and stabilized 1 hour later. Therefore, the research showed that moss played important roles in the absorption of rainwater within 1 hour of rainfall. The relation between water holding capacity and the immersion time can be described by y=a+bln (t).
